Question

Video store charges $12 for used games and $25 for new games. Jonathan has saved $300 to spend on video games. This scenario is represented by a linear equation.

12x + 25y = 300

x = number of used games

y = number of new games

How many games can Jonathan buy if he spends all his money on used games?

Answer 1

He can spend games at a rate of y = -0.48x + 12

Explanation:

12x + 25y = 300

Move the 12x on the other side.

25y = -12x + 300

Divide the 25y with everything.

y = -0.48x + 12
