Question

Marcus works as a salesman at a car dealership. He is paid a base salary of $1,445.74 each month, and he receives a commission of $108.68 for each vehicle he sells. If last month Marcus earned $6,010.30, how many cars did he sell last month?

Answer 1

First we need to set up an equation.

Let's call "x" the number of cars he sells.

Since he makes $1,445.74 right of the bat, it will be added in.  Then, 108.68 times the number of cars he sells.

$6010.3=1445.74+108.68x\\\\4564.56=108.68x\\\\42=x$

He sold 42 Cars.
