You and a friend are going bowling. renting shoes and the first game of bowling costs $7.50 for each person. if each
game after the first costs $2.50 per person, write a formula for the cost, c, per person after 9 games.

a) cg= $7.50 + (n - 1) . $2.50

b) cg= $2.50 + (n - 1). $7.50

c) cg= $5.00 + (n - 1). $7.50

d) cg= $5.00 + (n - 1) . $2.50

A) Cg= $7.50 + (n - 1) . $2.50

Step-by-step explanation:

The cost of Renting the shoes and the first game is a fixed cost, so it is a constant, $7.50.

And any other cost will be added to this.

The problem is looking for the cost after 9 games. But since the first game is already included in the $7.50, so we subtract the first game from the number of the total games played:

n - 1

where n = number of games played

Each succeeding game costs $2.50. So whatever games left to pay, we multiply it by $2.50.

( n - 1 )$2.50

Remember what was mentioned earlier, any other cost will be added to the constant and so:

Cg= $7.50 + ( n - 1 )$2.50

If you want to solve for the cost then just plug in the number of games:

n = 9

Cg= $7.50 + ( n - 1 )$2.50

Cg= $7.50 + ( 9 - 1 )$2.50

Cg= $7.50 + ( 8 )$2.50

Cg= $7.50 + $20.00

Cg = $27.50

its c
