Kinsley's Auto Wash earns revenues of $13 per customer. In all, how many customers does Kinsley's Auto Wash need to serve in order to have a total of $39 in revenue?

x = 3

Step-by-step explanation:

ok, so in this case we need to create an equation, we can do this based on the info u were given,

-it mentions "per customer" since the amount of customers is unknown we will replace that with x, 13 per customer, 13 per x so that would be 13x and it should equal the total 39 so the equation would be

13x=39

next, we need to solve and get x alone

-start by doing the opposite and dividing 13 by everything

13/13=0 it crosses out

39/13=3

so in this case, x = 3
