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

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
