5. A video store charges a monthly
membership fee of $12.00, but charges to
rent each movie is only $1.50 per movie.
Another store has no membership fee, but it
costs $3.00 to rent each movie. How many
movies need to be rented each month for
the total fees to be the same from either
company?

Respuesta :

Answer: 8 movies

12 + 1.50x = 3x

Move the variables to one side

12 = 1.50x

Isolate x

8 = x


Check:

3(8)= 24

12.00 + 1.50(8) = 24
