When Brandon went bowling, it cost $4.95 per game, plus a one-time fee to rent the shoes. Brandon played 5 games and paid $32. W
igomit [66]

Answer:

The linear equation used to find the cost to rent the shoes is 24.75+x=32

Cost to rent the shoes is $7.25.

Step-by-step explanation:

Given:

Cost of per game of bowling = $4.95

Number of games played = 5

Total money paid = $32

We need to find the cost to rent the shoes.

Solution:

Let the cost to rent the shoes be 'x'.

So we can say that;

Total money paid is equal to sum of Cost of per game of bowling multiplied by Number of games played and cost to rent the shoes.

framing in equation form we get;

5\times4.95+x=32\\\\24.75+x=32

Hence The linear equation used to find the cost to rent the shoes is 24.75+x=32

On solving the above equation we will find the value of 'x'.

Now we will subtract both side by 24.75 we get;

24.75+x=32-24.75\\\\x= \$7.25

Hence Cost to rent the shoes is $7.25.
