Question

You received a $27.00 credit for a website that sells movies and music files. A movie costs $4.50 to download and a song costs $.90. the equation 4.50m+0.9s=27.00, where m is movies and s is 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
