Answer:
Either location costs the same when they play 4 games
Explanation:
The total cost for playing putt-putt consists of fixed rentals and a variable amount per game.
On one location Ben and his friends can pay $2 rentals plus $7.50 per game.
If x is the number of games played, then the total cost at this location is:
C1(x) = 7.50x + 2
At another location, it would cost $8 for rentals plus $6 per game. The second function is:
C2(x) = 6x + 8
It's required to find the number of games x in order for either location to cost the same amount.
It can be done by equating both cost functions:
7.50x + 2= 6x + 8
Subtracting 2 and 6x:
7.50 - 6x = 8 -2
Operating:
1.5x = 6
Dividing by 1.5:
x = 6 / 1.5
x = 4 games
Either location costs the same when they play 4 games
