5. There are 200 kids in the 7th grade at Smith Middle School. If 25% of them purchase a school t-shirt that costs $20, how much money did the 7th grade spend on t- shirts?
25% of the kids bought a shirt so we need to find 25% of 200. .25x200 gets us the fact that 50 kids bought a shirt. Since a school shirt costs $20 and 50 kids bought one, do 50x20 to get 1000.
