Question

You received a $27.00 credit for a website that sells movie and music files. A movie costs $4.50 to downloadand a song costs $.90. The equation 4.50m  0.9s  27.00, where m is the number of movies and s is thenumber of songs, models the situation. How many songs can you download if you download two movies?

Answer 1

20 songs

Explanation:

you merely have to plug m = 2 into the equation and then solve for s

4.50m + .9s = 27.00

4.50(2) + .9s = 27.00

s = 20
