[Question]Marj has two $20 bills, three $5 bills, and $4.50 in loose coins in her wallet. If she buys a cake that costs $17.50, how much money will be left in her wallet?
[Answer]Two $20 bills amount to $20 x 2 = $40. Three $5 bills amount to $5 x 3 = $15. So, Marj has $40 + $15 + $4.50 = $59.50 in her wallet. If she buys a cake, she will be left with $59.50 - $17.50 = $42. The answer is 42.

Question: Hanna has twice as many erasers as Rachel. Rachel has three less than one-half as many erasers as Tanya has red erasers. If Tanya has 20 erasers, and half of them are red, how many erasers does Hanna have?
Answer: Half of Tanya's 20 erasers are red, so she has 20 / 2 = 10 red erasers. One - half as many erasers as Tanya has red erasers is 10 / 2 = 5 red erasers. Rachel's three less than one - half as many erasers as Tanya's red erasers, which is 5 - 3 = 2 erasers. Hanna has twice as many erasers as Rachel, for a total of 2 * 2 = 4 erasers. The answer is 4.
