Reasoning and answer: He is $45 short because 100 x .45 = 45. He earned $55 off goldfish because 100 - 45 = 55. He makes $.5 profit per goldfish because .75 - .25 = .5. He sold 110 goldfish that week because 55 / .5 = 110.
The answer: 110

Twice the current number of members now is 10 * 2 = 20 members. So, the club wants to have 20 + 5 = 25 members. Therefore, they need to get 25 - 10 = 15 members.
The answer: 15
Reverse engineering the question: A club is going to get additional members so that they will have 5 more than twice their current number of their members. If the club has 10 members now, how many additional members do they need?
Reasoning and answer: Before purchasing the beanie, Sarah has $7 + $14 = $21. Before purchasing the scarf, Sarah has $21 + $10 = $31. The total cost of the toy cars is 2 * $11 = $22. Before purchasing the toy cars, Sarah has $31 + $22 = $53.
The answer: 53

The number of bottles sold on Monday and Tuesday is 2445 + 900 = 3345 bottles. Each day of the rest of the week, 50 bottles were sold, that is 5 * 50 = 250 bottles sold. Now the total of bottles sold in a week is 3345 + 250 = 3595 bottles. The drugstore has in stock 4500 3595 = 905 bottles. Finally the drugstore has 905 + 650 the supplier brought = 1555 bottles at the end of the week.
The answer: 1555

On Saturday, the supplier delivers an order for 650 bottles. How many bottles of sanitizer gel does the Drugstore have at the end of the week?
Reasoning and answer: First find the monthly late fee for the first bill: $200 * 10% = $20. Then multiply that by the number of months the bill is overdue: $20 / month * 2 months = $40. Then find the total late fee for the second bill the same way: $50 / month * 6 months = $300. Then find the third bill's second late fee: 2 * $40 = $80. Then add all the bill amounts and late fees to find the total cost: $40 + $200 + $300 + $130 + $40 + $80 + $444 = $1234.
The answer: 1234

Reasoning and answer: First find how many minutes Jenna tans each of the first two weeks: 30 minutes / day * 2 days / week = 60 minutes / week. Then multiply that number by the number of weeks to find how many minutes Jenna tans in the first half of the month: 60 minutes / week * 2 weeks = 120 minutes. Then subtract that time from the total time Jenna can spend tanning to find how many more minutes she can tan: 200 minutes - 120 minutes = 80 minutes.
The answer: 80
