Answer:
88 Spray bottles
Explanation:
You need to find how many spray bottles Ms. Romero filled. But first, you need to know how much cleaning solution she had in all.
Ms. Romero mixed 1 gallon of concentrated cleaner with 10 gallons of water. So, she had 11 gallons of cleaning solution in all.
Ms. Romero filled each spray bottle with 1 pint of cleaning solution. So, find how many pints are in 11 gallons. There are 2 pints in a quart, and there are 4 quarts in a gallon. That means there are 8 pints in a gallon, so multiply 11 gallons by 8.
11×8=88
Ms. Romero had 88 pints of cleaning solution. Since she filled each spray bottle with 1 pint, she filled 88 spray bottles.
