Well I used to have questions like having to add together a base price of something + per something product of a multiplication part or something.. Like... "Bob the plummer charges a base price of 20 dollars including 5 dollars an hour. So if Bob works on Larry's toiletries and pipes for two hours, what is the cost?" kind of thing :3

"...at how many gallons would it start being a bargain if you were paying $3.50 per gallon instead."
