Question

The Game Exchange game rental store charges an annual fee of $9 and $5.25 per game rented. The Fun Box charges an annual fee of $17 plus $2.50 per game.
(1) Write an equation for each game rental store.
(2) When would each store be the better choice and explain why
(3) How would you graph this using a graphing calculator?

Answer 1

so for number 1 the game exchange rental store there is a fee of 9 bucks so that should be your y-int and 5.25 per game is always changing so that is your slope
putting in y=mx + b you get
y = 5.25x + 9
same for the fun box it will be y=2.50x + 17

for number 2 when each store is the better choice is when both of these lines intersect each other so set those 2 equal to each other
5.25x + 9 = 2.50x + 17
simiplify and you will get x = 2.91

and you can just put those 2 equations in the graphing calc
so press table and put in the equations then press graph

Answer 2

Thank you so much c:
