Question: Vanessa wants to buy a dress she saw at the mall, which costs $80, and she already has $20 in savings. Her parents give her $30 every week, but she also spends $10 each weekend at the arcades. How many weeks will she have to wait until she can gather enough money to buy the dress?
Answer: Vanessa needs $80 – $20 = $60 to buy the dress. She manages to gather $30 - $10 = $20 each week. The number of weeks she has to wait is 60 ÷ 20 = 3 weeks. The answer is 3.
[Question]The cost of building a certain house in an area is 100,000 more than the construction cost of each of the houses in the area. But it sells for 1.5 times as much as the other houses, which sell at $320,000 each. How much more profit is made by spending the extra money to build?
[Answer]The house cost 320,000 * 1.5 = $480,000. So it is worth 480,000 - 320,000 = $160,000 more than other houses. So the profit is 160,000 - 100,000 = $60,000 more. The answer is 60000.
Q: Nathan planted 5 strawberry plants and 7 tomato plants. He harvested 14 strawberries from each plant and 16 tomatoes from each plant. He then distributed the strawberries and tomatoes into baskets of 7. He sold a basket of strawberries for $9 and a basket of tomatoes for $6. How much money does Nathan make from his harvest?
A: Nathan harvested a total of 5 x 14 = 70 strawberries. He harvested a total of 7 x 16 = 112 tomatoes. He was able to fill 70 / 7 = 10 baskets with strawberries. He was able to fill 112 / 7 = 16 baskets with tomatoes. He made 10 x $9 = $90 from the strawberries. He made 16 x $ 6 = $96 from the tomatoes. All together, he made $90 + $96 = $186 from his harvest. The answer is 186.
Question: John invests in a bank and gets 10% simple interest. He invests $1000. How much money does he have after 3 years?
Answer: He gets 1000 * .1 = $100 a year. So after 3 years, he gets 100 * 3 = $300. So he has 300 + 1000 = $1300. The answer is 1300.
[Question]A flower shop sells bouquets of roses, which each contain 12 roses, and bouquets of daisies, which each contain an equal amount of daisies. The flower shop sells 20 bouquets today. 10 of these were rose bouquets and the remaining 10 bouquets were daisy bouquets. If the flower shop has sold 190 flowers in total today, how many daisies are in each bouquet of daisies?
[Answer]The flower shop sold 10 bouquets * 12 roses / bouquets = 120 roses. This means they sold a total of 190 flowers – 120 roses = 70 daisies. Therefore, each daisy bouquet contains 70 daisies / 10 bouquets = 7 daisies per bouquet. The answer is 7.
[Question]Bill composes 20 total math questions for money. Ryan composes twice as many problems as Bill, and Frank composes 3 times as many as Ryan. Assuming each person has to compose 4 different types of math problems in equal proportion out of the total amount, how many problems of each type does Frank compose?
[Answer]
Since Ryan composes twice as many problems as Bill's total of 20, this means Ryan composes 20 * 2 = 40 problems. Frank composes 3 times as many as Ryan does, so this means Frank composes 40 * 3 = 120 problems. Since Frank needs to submit 4 types of problems in equal proportion out of his total, this means he needs to make 120 / 4 = 30 problems of each type. The answer is 30.
