The original price of the pants were 48 dollars
M=cost per movie
v=cost per video game
2m+5v=33
8m+3v=30
use elimination
eliminate movies
mutliply first equation by -4 and add to 2nd
first equation becomes -8m-20v=-132
add the 2 equations
-8m-20v=-132
<u>8m+3v=30 +</u>
0m-17v=-102
-17v=-102
divide both sides by -17
v=6
subsiutute back
2m+5v=33
2m+5(6)=33
2m+30=33
minus 30 both sides
2m=3
divide 2
m=1.5
