movies: x
video games: y
x+y = 250 subtract x from both sides: y = 250-x
next:
3x+2.50y = 650 substitute for y:
3x+2.50(250-x) = 650
3x+625-2.50x = 650
0.50x = 25
x = 50 this is how many movies were rented
250-50= 200 games were rented
-------------------------------------------------
Check:
50*3 = 150
200*2.50 = 500
-----------------
Total : 650 Correct
