Ответ:
Tommy has to clean at least 76 pools to make a total of $1500.
Step-by-step explanation:
Money Tommy needs to buy the car=$1500
Money earned for mowing 1 line=$20
Money earned for cleaning 1 pool=$9
Number of lines mowed=41
Money earned by mowing alone=41×20
=$820
Money to be earned by cleaning pools=1500-820
=$680
So,number of pools to be cleaned=![\frac{680}{9}](/tpl/images/0399/7374/19067.png)
=75.555
Hence ,Tommy has to clean at least 76 pools to make a total of $1500.
