Q: Janet buys 45-pound containers of cat litter for $21 each. If her cat litter box holds 15 pounds of cat litter, and she changes out the litter weekly, how much will it cost, in dollars, for her to buy enough litter to last 210 days?
A: If she changes the box weekly, then in 210 days, she will change the box 210 / 7 = 30 times. At 15 pounds of litter for every box change, she will require 30 * 15 = 450 pounds of cat litter in 210 days. If she buys 45 - pound containers, then for 450 pounds she will need to buy 450 / 45 = 10 containers of litter. At $21 per container, to buy enough cat litter for 210 days, it will cost 10 * $21 = $210. The answer is 210.
Question: Kristy, a sales representative earns a basic salary of $7.50 per hour plus a 16% commission on everything she sells. This month, she worked for 160 hours and sold $25000 worth of items. Her monthly budget for food, clothing, rent, transportation, bills and savings is 95% of her total monthly earnings and the rest will be put towards insurance. How much did she allocate to insurance?
Answer: Kristy earns a basic salary of $7.50 x 160 = $1200. Her total commission is $25000 x 16 / 100 = $4000. Thus, her total earning is $1200 + $4000 = $5200. Her monthly budget aside from the insurance is $5200 x 95 / 100 = $4940. Therefore, she allocated $5200 - $4940 = $260 on insurance. The answer is 260.
[Question]Jean has 60 stuffies. She keeps 1/3 of them and then gives away the rest. She gives 1/4 of what she gave away to her sister Janet. How many stuffies did Janet get?
[Answer]Jean kept 60 / 3 = 20 stuffies. That means she gave away 60 - 20 = 40 stuffies. So Janet got 40 / 4 = 10 stuffies. The answer is 10.
Q: The doctor told Barry to take vitamin D3 for 180 days to help protect him from infections. The pharmacy only sold vitamin D3 in bottles containing 60 capsules, with a daily serving size of 2 capsules. How many bottles would Barry need to buy to have enough servings to last for 180 days?
A: If each serving size is 2 capsules, a 60 - capsule bottle of vitamin D3 would contain 60 / 2 = 30 servings. Using 30 - serving bottles, to last 180 days, it would take 180 / 30 = 6 bottles of vitamin D3. The answer is 6.
Question: For the funfair, the school organizers ordered 30 rolls of tickets. Each roll of tickets has 100 tickets. The 4th graders bought 30% of the tickets while the 5th graders bought 50% of the remaining tickets. Then the 6th graders bought a total of 100 tickets. How many tickets were left unsold?
Answer: There were a total of 30 x 100 = 3000 tickets ordered by the school organizers. The 4th graders bought 3000 x 30 / 100 = 900 tickets. So, there were 3000 - 900 = 2100 tickets left for the other two grade levels. The 5th graders bought 2100 x 50 / 100 = 1050 tickets. So, 2100 - 1050 = 1050 tickets were left then. Since 100 tickets were bought by the 6th graders, therefore 1050 - 100 = 950 tickets were left unsold. The answer is 950.
