[Question]: If Pete read twice as many books as Matt did last year, and this year he doubles that number while Matt reads only 50% more, how many books does Pete read across both years if Matt read 75 books in his second year?
[Answer]: First, we need to find the amount Matt read both years to establish what Pete read, so to find Matt's first - year total we multiply 75 / 1.5 = 50 books the previous year. Since Pete read twice as many books as Matt did in the first year, and Matt's first - year total is 50, this means Pete read 50 * 2 = 100 books his first year. Since Pete doubled the number of books he read the following year, this means Pete read 100 * 2 = 200 books the following year. We add the two years of Pete's reading together to find 200 + 100 = 300 books read in total.
So the answer is 300.

[Question]: A couple agreed to split their expenses equally, including the salary of their house help. While doing her job, the house help had an accident; thus, she underwent a medical procedure which cost her $128. The couple decided to pay half of the medical expenses and the other half will be deducted from her $160 salary. If the husband paid for the entire half of the hospital bill, how much does he still need to pay so that they split the expenses for the house help equally?
[Answer]: The amount that the couple would cover for the hospital bill is $128 / 2 = $64. The couple's total expenses (salary and hospital bill) is $160 + $64 = $224. So each of them should give $224 / 2 = $112 in total. Since the husband paid the entire half of the hospital bill already ($64), he still needs to pay $112 - $64 = $48.
So the answer is 48.

There will be $100 / $50 = 2 pieces of $50 when $100 is changed to $50 bills. Half of $100 is $100 / 2 = $50. So there will be $50 / $10 = 5 pieces of $10 when $50 is changed to $10 bills. The remaining $50 will be changed to $5 bills so there will be $50 / $5 = 10 pieces of $5 bills. So in total, Lorie will have 2 $50 bills + 5 $10 bills + 10 $5 bills = 17 pieces of bills.
So the answer is 17.
