The fun guys game rental store charges an annual fee of $20 plus $6.50 per game rented. the game bank charges an annual fee of $50 plus $3.50 per game. for how many game rentals will the cost be the same at both stores? what is that cost?

In order to find the breakeven number of game rentals, we need to find the point at which the costs are equal. To do this, we set two expressions as a function of the number of games, equate them, and solve.
   For Fun Guys, cost C = 20 + 6.5g, where g is the number of games
 For Game Bank, C = 50 + 3.5g
Equating -> 20 + 6.5g = 50 + 3.5g -> 3g = 30 -> g = 10
   At 10 games, the cost will be the same for both stores, and that cost is 50 + 3.5* 10 = 20 + 6.5*10 = $85.
