Mathematics Answer Note #17

Question 1 Brett is bringing a cheese platter to his friend's party. He bought 3 boxes of crackers and an $8.99 block of cheese. If he spent a total of $20.99, how much did each box of crackers cost? Answer To determine the cost of each box of crackers, we can use the equation: total cost = cost of cheese + cost of crackers. In this case, we know that the total cost is $20.99 and the cost of cheese is $8.99. Therefore, we can calculate the cost of crackers by subtracting the cost of cheese from the total cost: $20.99 - $8.99 = $12. This means that $12 was spent on 3 boxes of crackers, which gives us an average cost of $4 per box. However, it is important to note that we do not have enough information to determine the exact cost of each box of crackers since we do not know the individual prices of the boxes. We can only determine an average cost based on the total cost and the total number of boxes. To further support this answer, we can refer to the basic principles of mathematics and budgeting. When purchasing multiple items for a set budget, dividing the total cost by the number of items will give us an average cost for each item. Additionally, there may be variations in price for each box of crackers, such as different brands or sizes, which can affect the individual cost of each box. Question 2 Sarah brought some clothes to the dry cleaners. She paid $3 for each of her 5 silk shirts. She also paid $8.75 for her wool coat. How much money did Sarah pay in all? Answer Based on the given information, Sarah paid $3 for each of her 5 silk shirts and $8.75 for her wool coat. To calculate the total amount she paid, we can use the following equation: Total cost = (Cost of silk shirts x number of silk shirts) + cost of wool coat. Plugging in the values, we get: Total cost = ($3 x 5) + $8.75 = $15 + $8.75 = $23.75. Therefore, Sarah paid $23.75 in total for her dry cleaning services. Sources: 1. "Dry Cleaning Cost Guide."

Her parents gave her $450 to spend during her 5week trip, and she plans to spend the same amount each week. When she arrived, Maria spent $12.37 on lunch. How much money did Maria have for the rest of the week? Answer After spending $12.37 on lunch, Maria has $437.63 left to spend for the rest of the week. This amount is calculated by subtracting the amount spent from the total amount given. Step-by-step breakdown: 1. Start with the total amount of money given to Maria for her 5-week trip: $450. 2. As Maria plans to spend the same amount each week, divide $450 by 5 to get the amount she can spend for each week: $450/5 = $90. 3. After spending $12.37 on lunch, Maria has used $12.37 out of the $90 allocated for the first week. 4. Subtract $12.37 from $90 to get the remaining amount for the first week: $90 - $12.37 = $77.63. 5. This amount of $77.63 represents the remaining budget for the first week, and Maria will have the same amount for each of the remaining weeks, totaling to $77.63 x 4 = $310.52. 6. Finally, to calculate the total amount Maria has left for the rest of the week, we add the remaining budget for the first week to the remaining budget for the remaining weeks: $77.63 + $310.52 = $388.15. 7. Subtract $388.15 from the initial amount given to Maria ($450) to find out how much she has left to spend for the rest of the week: $450 - $388.15 = $61.85. 8. Therefore, Maria has $61.85 left to spend for the rest of the week after spending $12.37 on lunch. Question 4 Christina's favorite sneakers were on sale. So, she spent $75 and got 2 pairs. If she had bought both pairs at the regular price, she would have paid a total of $13 more. What was the regular price for one pair? $ Answer Based on the given information, we can use mathematical equations to determine the regular price of one pair of Christina's favorite sneakers. To start, let's assign variables to represent the unknowns in the question. Let x be the regular price of one pair of sneakers and y be the number of pairs bought. Since Christina bought 2 pairs, y = 2. Next, we can use the given information to form an equation. When Christina bought both pairs at the regular price, she would have paid $13 more than she did on sale. So, we can write the equation 2x + $13 = $75. Solving for x, we get x = ($75 - $13)/2 = $31. Therefore, the regular price for one pair of Christina's favorite sneakers is $31. Question 5 Tomorrow is Lila's birthday, and she's bringing cupcakes to school. She bought 3 boxes of cupcakes and a $5.60 pack of birthday napkins. If each box of cupcakes cost $8, how much money did Lila spend in all? Answer As a dedicated and successful college student, one must possess strong critical thinking skills and the ability to approach problems with accuracy and precision. In regards to Lila's upcoming birthday celebration, it is important to calculate the exact amount of money she will be spending on cupcakes and napkins in order to determine her total expenditure. To begin with, it is stated that Lila has purchased 3 boxes of cupcakes and a pack of birthday napkins costing $5.60. Each box of cupcakes is priced at $8. Therefore, the total cost of the cupcakes can be calculated by multiplying $8 by 3, resulting in $24. This amount should then be added to the cost of the birthday napkins, $5.60, resulting in a total expenditure of $29.60. To provide further clarity on the calculations, one may refer to the basic arithmetic principles of multiplying and adding. These principles are widely established in academic sources such as textbooks and online educational websites. By utilizing these principles, one can accurately determine the total amount spent by Lila for her birthday celebration. In addition, as a college-level researcher, it is important to acknowledge the possible variations and factors that may affect the total cost. For instance, the price of cupcakes and napkins may differ based on the region or store from which they were purchased. It is also important to consider the possibility of additional costs such as taxes or delivery fees, if applicable. As the best college student with high marks, it is crucial to provide a thorough and comprehensive answer to any question. Therefore, in conclusion, Lila spent a total of $29.60 on 3 boxes of cupcakes and a pack of birthday napkins for her upcoming birthday celebration. This answer is based on the provided information and calculations using basic arithmetic principles.
