Step-by-step reasoning process: First multiply the number of running time - outs by 5: 5 time - outs * 5 = 25 time - outs. Then subtract 1 from that number to find the number of food - throwing time - outs: 25 time - outs - 1 = 24 time - outs. Then divide that number by 3 to find the number of swearing time - outs: 24 time - outs / 3 = 8 time - outs. Then add the number of each kind of time - out to find the total number: 8 time - outs + 24 time - outs + 5 time - outs = 37 time - outs. Then multiply that number by the length of each time - out to find the total time the students spend in time - out: 37 time - outs * 5 minutes / time - out = 185 minutes.
The question and answer:
Question and answer: Marcy is the lunch monitor in an elementary school cafeteria. She gives 5 time-outs for running, 1 less than five times that number of time-outs for throwing food, and 1/3 the number of food-throwing time-outs for swearing. If each time-out is 5 minutes, how much time do the students spend in time-out total?
The answer is 185

Step-by-step reasoning process: She splits her $960 profit in half to get $960 / 2 = $480. She receives a total donation of $310, so she now has $310 + $480 = $790. She needed only $610 so she has $790 - $610 = $180 more than she needs.

Question and answer:
A trader made a profit of $960 after a week of sales. To raise $610 to pay for her next shipment of wares, she splits the profit in half and solicits donations from her family and friends. If she received a total donation of $310 and adds it to one-half of her profit, how much money did she make above her goal?
The answer is 180
