Answer:
Step-by-step explanation:
Let x represent the number of car washes that he gets in a month with either packages.
Package A is an unlimited number of car washes for a month, and it costs $35 with no additional charges. It means that the cost of x car washes is $35.
Package B is $22 for the month plus $1.50 per car wash. It means that the cost of x car washes with package B is
1.5x + 22
For Package A to be the better deal, the equation to find the the number of car washes he would need to get in a month is
1.5x + 22 > 35
1.5x > 35 - 22
1.5x > 13
