Question 457367: A new edition of a video game costs $60 but it's previous version only costs $40. If 15 games are sold for $840 how many copies of the newest game sold? Five step method. Show work please :) Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! I will assume that you mean that 15 games were sold and some are old edition and some are new edition.
x+y=15
40x+60y=840
x=3 at $40
y=12 at $60 new edition
check
3*40+12*60=840
120+720=840
ok
