Q: Davonte is trying to figure out how much space his art collection takes up. He measures his paintings and finds he has three square 6-foot by 6-foot paintings, four small 2-foot by 3-foot paintings, and one large 10-foot by 15-foot painting. How many square feet does his collection take up?
A: His square paintings take up 36 square feet each because 6 x 6 = 36. His small paintings take 6 square feet each because 2 x 3 = 6. His large painting takes up 150 square feet because 10 x 15 = 150. Combined, his square paintings take up 108 square feet because 3 x 36 = 108. Combined, his small paintings take up 24 square feet because 4 x 6 = 24. In total, his paintings take up 282 square feet because 150 + 108 + 24 = 282. The answer is 282.
Question: Candice buys all the bread she and her family needs for the week from a local bakery. She needs 2 loaves of white bread for sandwiches that cost $3.50 each. She also needs a baguette that costs $1.50 and 2 loaves of sourdough bread that cost $4.50 each. She also treats herself to a $2.00 almond croissant each visit. How much does Candice spend at the bakery over 4 weeks?
Answer: 2 loaves of white bread are $3.50 each so they cost 2 * 3.50 = $7.00. 2 loaves of sourdough bread are $4.50 each so they cost 2 * 4.50 = $9.00. The white bread comes to $7.00, the sourdough is $9.00 and she gets a baguette for $1.50 and a croissant for $2.00 so she spends 7 + 9 + 1 + 2 = $19.50 per week. If she buys this same order of $19.50 every week for 4 weeks then she spends 19.50 * 4 = $78.00 over 4 weeks. The answer is 78.
[Question]Because of the migration of salmon, the total number of salmon in river Trout has increased by ten times the number initially in the river. If there were 500 salmons initially, calculate the total number of fish in the river now.
[Answer]If the number of salmons in the river increased by ten times the number initially there, then 500 * 10 = 5000 new salmons migrated up the river. The total number of salmon in the river now is 5000 + 500 = 5500. The answer is 5500.
Q: Jerry works five days a week as a waiter and earns a variable amount of tips every night. The past four nights, he earned $20, $60, $15, and $40. How much does he need to earn tonight if he wants to make an average of $50 in tips per night?
A: The total money Jerry needs to make for 5 days to get $50 per night is 5 nights * $50 / night = $250. His total earnings for the past four days is $20 + $60 + $15 + $40 = $135. So, Jerry needs to earn $250 - $135 = $115 in tips tonight. The answer is 115.
Question: A class is 40% boys. The rest are girls. Every boy in class gets an 80% on the math test. Every girl gets a 90%. What is the class average on the test?
Answer: The class is 60% girls because 100 - 40 = 60. The class average is 86% because .4(80) + .6(90) = 86. The answer is 86.
Q: Betty and Dora started making some cupcakes at the same time. Betty makes 10 cupcakes every hour and Dora makes 8 every hour. If Betty took a two-hour break, what is the difference between the number of cupcakes they made after 5 hours?
A:
Dora made 8 cupcakes per hour for 5 hours for a total of 8 * 5 = 40 cupcakes. Betty took a 2 - hour break so she spent 5 - 2 = 3 hours making cupcakes. Betty made 10 cupcakes per hour for 3 hours for a total of 10 * 3 = 30 cupcakes. The difference between the number of cupcakes they made is 40 - 30 = 10 cupcakes. The answer is 10.
