Question

Stephanie is registering her son for swim lessons. There is a one time $45 registration fee plus a $20 fee per lesson. Stephanie paid a total of $225. For how many lessons did Stephanie register? Write an equation to represent the problem and solve it.

Answer 1

the equation is 45 + 20x= 225 and her son had a total of nine (9) classes.

Explanation:

45 + 20x = 225 is the equation.

to solve it, we do 225-45=180

then, 180/20= 9

so x = 9
