[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]Sheila, Purity, and Rose want to rent a house. Sheila has offered to pay five times Purity’s share of the rent. Rose can only afford thrice what Purity pays. If Rose’s share is $1,800, what is the total house rent?
[Answer]Purity will pay a third of Rose's share, which translates to 1800 / 3 = 600 dollars. Sheila has offered to pay 5 * 600 = 3000 dollars. Combining everyone’s share of the rent will give a total of 600 + 3000 + 1800 = 5400 dollars. The answer is 5400.
Q: John ends up damaging his hearing aids. He needs to replace both of them. They cost $2500 each. Insurance covers 80% of the cost. How much does he personally have to pay?
A: The cost of the hearing aids is $2500 * 2 = $5000. So insurance covers $5000 * .8 = $4000. That means it cost him $5000 - $4000 = $1000. The answer is 1000.
Question: Grandpa Lou enjoys watching movies on the Hallmark channel, where every movie lasts 90 minutes. If, on Tuesday, he watched several full-length movies on the Hallmark channel for a total of 4 hours and 30 minutes, and then on Wednesday he watched on the same channel twice as many movies as he did on Tuesday. What is the maximum number of full-length movies Grandpa could have watched during these two days?
Answer:
4 hours and 30 minutes is the same as 4 * 60 + 30 = 270 minutes. At 90 minutes per movie, Grandpa could watch a total of 270 / 90 = 3 entire movies in 4 hours and 30 minutes. On Wednesday, he watched 2 * 3 = 6 movies. Thus, during these two days, he could have watched as many as 3 + 6 = 9 movies. The answer is 9.
