We have a question: Josh has some money. He spent $1.75 on a drink, and then spent another $1.25. If he had $6 left, how much money, in dollars, did Josh have at first?
And an answer: 9
So how you got the answer?
Josh spent 1.75 + 1.25 = 3 dollars in total. Josh had 6 + 3 = 9 dollars at first.

We have a question: On their way driving to Los Angeles, Benjamin and James see lots of billboard ads. Curious, Benjamin starts to count how many they see. In the first hour once he starts counting he counts 17 billboards. In the second hour once he starts counting he sees 20 billboards. In the third hour he sees 23 billboards. James asks Benjamin the average number of billboards they've seen per hour. What should Benjamin tell him?
And an answer: 20
So how you got the answer?
Benjamin counts 17 + 20 + 23 = 60 billboards total on the way to Los Angeles. Benjamin saw those billboards over 3 hours, so the average number of billboards per hour they saw 60 / 3 = 20 billboards per hour.

We have a question: Wendy went to the dentist for a cleaning, two fillings, and a tooth extraction. The dentist charges $70 for a cleaning and $120 for a filling. Wendy's dentist bill was five times the cost of a filling. What did Wendy pay for the tooth extraction?
And an answer: 290
So how you got the answer?
Wendy's dentist bill was 5 * $120 = $600. She got two fillings at a cost of 2 * $120 = $240. Thus, Wendy paid $600 - $240 - $70 = $290 for the tooth extraction.
