Games r us offers two plans for renting video games . plan a charges a one time memebership fee of $24 plus $1 for each game rental plan b charges $3 per game rental . write an equation for each company . then graph the results . for what number of games is the cost of both plans the same ?

Plan A:  x + 24
Plan B:  3x

The graphs meet at (12,36).

Part A & B:

Solve for y in the first equation

Plot both lines on the same graph and the point at which they intersect is your answer.

Part C:
replace the variable y in the first equation with the expression in the second equation. you should have this equation containing only x values

solve for x now.
plug the x value you have into equation 2 and solve for y.

the x,y pair should should be equal to the point from the graph.
