Question

A movie rental website charges $5.00 per month for membership and $1.25 per movie.

Answer 1

To solve this problem, I would transfer this word problem into an equation with variables.

let the variable m stand for the amount of movies andrew rents.

5.00+1.25m=16.25

Now that we have our equation, we can just solve it like any other equation.
To do this, first, we would subtract 5.00 from both sides, resulting in the equation

1.25m=11.25

Next, we would divide both sides by 1.25, resulting in your final answer

m=9.

This means that Andrew rented 9 movies if his total was 16.25
