[Question]Bryan starts exercising at home during quarantine. To start, he decides to do 3 sets of 15 push-ups each. Near the end of the third set, he gets tired and does 5 fewer push-ups. How many push-ups did he do in total?
[Answer]In total, Bryan would have done 3 sets * 15 push - ups / set = 45 push - ups. Subtracting the push - ups he didn't do in the third set, Bryan did 45 push - ups - 5 push - ups = 40 push - ups. The answer is 40.

[Question]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?
[Answer]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. The answer is 180.
