[Question]Rhett has been late on two of his monthly rent payments, but his landlord does not charge late fees and so he will be able to pay their total cost with 3/5 of his next month's salary after taxes. If he is currently paid $5000 per month and has to pay 10% tax, calculate his rent expense per month?
[Answer]If Rhett is currently paid $5000 per month, he pays 10 / 100 * $5000 = $500 in taxes. Rhett has been late on two of his monthly rent payments and plans to pay them with 3 / 5 * $4500 = $2700 from his salary after taxes. If he is to pay $2700 for two late monthly rent payments, his monthly rent expense is $2700 / 2 = $1350. The answer is 1350.

[Question]55% of Toby's friends are boys and the rest are girls. If he has 33 friends who are boys, how many friends does he have who are girls?
[Answer]Toby has 60 friends because 33 / .55 = 60. 45% of his friends are girls because 100 - 55 = 45. He has 27 friends who are girls because 60 x .45 = 27. The answer is 27.

[Question]Violet is trying to figure out whether she should buy a family pass to the aquarium for $120 or pay for tickets separately. If adult tickets cost $35 and children's tickets cost $20, and Violet's family has 1 adult and 6 children, how much will she pay if she buys separate tickets?
[Answer]First find the total cost of the children's tickets: 6 children * $20 / child = $120. Then add the cost of the adult ticket to find the total cost: $120 + $35 = $155. The answer is 155.
