a paint store has 35 gallons of paint in storage, 2/5 of which are for outdoor use. the others are for indoor use. if each gallon costs $22, what is the total cost of indoor paint in storage?
You need 3/5 of the 35 gallons of paint, so all you need to do is divide 35 by 5 to get 7 and multiply that by 3 to get 21. 3/5 of 35 is 21. Then, if each gallon is $22, you just multiply 21x22 to get your cost.
