Tracy's swimming pool requires 3 quarts of bacteria-cleaning agent 5 times a month. how many gallons of this agent will tracy use during june, july, and august?

5 times a month for 3 months 5 x 3 = 15
15 x 3 = 45
1 quart = .25 gallons 
45 quarts =11.25 gallons 
your answer is 11.25

Okay, so 4 quarts are in a gallon right? each month she uses 15 quarts because 3 x 5 = 15. Multiply that by 3 for the three month time span and you get 45. like I said, there's 4 quarts in a gallon.. Divide 45 by 4 and you get 11.25 roughly. there you go. Hope this helped

Look i don’t know the answer to this but someone else will so just wait a little bit longer
