Question

a video game system and several games cost $628 the cost of the games is 3 times the cost of the system find the cost of the system, and the games?

Answer 1

Games: $471; System: $157

s = cost of the system, and g = cost of the games
It is given that s+g = 628
and g=3*s

s+3*s = 628
4s = 628
s = 157

s+g = 628
157+g= 628
g= 628-157
g= 471
