[Question]A baker is comparing the day’s sales to his daily average. He usually sells 20 pastries and 10 loaves of bread. Today, he sells 14 pastries and 25 loaves of bread. If pastries are sold for $2 and loaves of bread are sold for $4, what is the difference, in dollars, between the baker’s daily average and total for today?
[Answer]The daily average sales of pastries amounts to 20 pastries * $2 / pastry = $40. The daily average sales of bread amounts to 10 loaves of bread * $4 / loaf = $40. Therefore, the daily average is $40 + $40 = $80. Today’s sales of pastries amounts to 14 pastries * $2 / pastry = $28. Today’s sales of loaves of bread amounts to 25 loaves of bread * $4 / loaf = $100. Therefore, today’s sales amount to $28 + $100 = $128. This means the total difference between today’s sales and the daily average is $128 – $80 = $48. The answer is 48.
Q: Jason is making sand art. He wants to fill a rectangular patch 6 inches by 7 inches with blue sand, and a square path 5 inches by 5 inches with red sand. If it takes 3 grams of sand to fill one square inch, how many grams of sand does Jason need?
A: First find the area of the first patch: 6 inches * 7 inches = 42 inches. Then find the area of the second patch: 5 inches * 5 inches = 25 inches. Then add those two amounts to find the total area Jason needs to cover: 42 inches + 25 inches = 67 inches. Then multiply that area by the number of grams per square inch to find the total amount of sand needed: 67 inches * 3 grams / square inch = 201 grams. The answer is 201.
Question: A park has 50 benches with a capacity of 4 people each. On a Sunday afternoon, 80 people were sitting on the benches. What's the number of available spaces on the benches that other people can sit on before the carrying capacity of the benches is full?
Answer: In the park, 50 benches with a capacity of four people each have a total capacity of 50 * 4 = 200 sitting spaces. If 80 people are already using spaces, the number of empty spaces is 200 - 80 = 120. The answer is 120.
[Question]In the class of 24 students, half are doing silent reading, and a third are playing board games. The rest are catching up on homework. How many students are catching up on homework?
[Answer]24 / 2 = 12 students are doing silent reading. 24 / 3 = 8 students are playing board games. So 12 + 8 = 20 students are accounted for. Then 24 - 20 = 4 students are catching up on homework. The answer is 4.
[Question]Jude bought three chairs for his house, all at the same price. He also bought a table that costs $50 and two sets of plates at $20 for each set. After giving the cashier $130, Jude got a $4 change. How much did each of the chairs cost?
[Answer]
The two sets of plates amount to $20 x 2 = $40. So the table and the two sets of plates amount to $50 + $40 = $90 in all. Since Jude received a $4 change, then he paid a total of $130 - $4 = $126 for the chairs, tables, and plates. Thus, the three chairs cost $126 - $90 = $36. Therefore, each chair cost $36 / 3 = $12. The answer is 12.
