Q: Jane's mother agreed to pay her $.50 for every flower bulb that Jane planted. Jane planted 20 tulip bulbs and half that amount of iris bulbs. She also planted 30 daffodil bulbs and three times that amount of crocus bulbs. How much money did Jane earn?
A: 20 tulip bulbs at $.50 each is 20 * .50 $10.00. She planted half that amount of iris' so 20 / 2 = 10 bulbs. 10 iris bulbs at $.50 each is 10 * .50 = $5.00. 30 daffodil bulbs at $.50 each is 30 * .50 = $15.00. She planted three times that amount of crocus bulbs to 30 * 3 = 90 bulbs. 90 crocus bulbs at $.50 = $45.00. All total, she earned 10 + 5 + 15 + 45 = $75.00. The answer is 75.

Q: Jenny's local library received 50 visitors on Monday. On Tuesday, the library received twice that number. On the remaining days of the week, an average of 20 visitors went to the library. What's the total number of visitors who went to the library that week?
A: On Monday, there were 50 visitors. On Tuesday, there were twice as many, so 2 * 50 = 100 visitors. The total number of visitors after Tuesday will be 100 + 50 = 150 visitors. For the remaining 5 days, an average of 20 visitors attended, giving a total of 5 * 20 = 100 visitors. The total number of visitors who visited the library for the week was 100 + 150 = 250 visitors. The answer is 250.

Q: Isabelle gets a job so she can save enough money to go to a concert with her two brothers. Her ticket costs $20. Her brothers both get the children’s discount, and each of their tickets cost $10. Her brothers have saved $5 between the two of them and Isabelle has saved $5. If her job pays $3 per week, how many weeks must she work to afford the tickets?
A:
The tickets for both of her brothers will cost her $10 * 2 = $20. To buy tickets for all of them, it will cost Isabelle $20 + $20 = $40. Between all of them, they have saved a total of $5 + $5 = $10. Since they have already saved $10, she needs to earn an additional $40 - $10 = $30 to afford the tickets. Since she makes $3 per week, it will take her $30 / ($3 / week) = 10 weeks to save enough money for all of the tickets. The answer is 10.
