Video Store A charges a $15.00 account

setup fee and $1.75 per movie rental. Video

Store B charges a $7.50 account setup fee

and $2 25 per movie rental. What number

of movie rentals will make the total cost of

renting movies from Video Store A equal to

the total cost of renting movies from Video

Store B?

D David on

A

Step-by-step explanation:

video store A : 15 + 1.75m

video store B : 7.5 + 2.25m

15 + 1.75m = 7.5 + 2.25m

15 - 7.5 = 2.25m - 1.75m

7.5 = 0.50m

7.5 / 0.50 = m

15 = m <== = there would have to be 15 movie rentals to make them equal

check ...

15 + 1.75m 7.50 + 2.25m

15 + 1.75 (15) = 7.50 + 2.25 (15) =

41.25 41.25

yep ... it checks out
