Answer 1

The total cost is $95.32.

Explanation:

Given:

Total came to $76.75. There is an 8% sales tax and 15% tip.

Now, to find the total cost.

8% sales tax is there so we calculate the amount after adding sales tax:

$76.75 + 8% of $76.75

`76.75+(8)/(100)* 76.75`

`76.75+0.08* 76.75`

`76.75+6.14`

`82.89`

The cost after sales tax is $82.89.

Now, the cost after 15% tip:

$82.89 + 15% of $82.89

`82.89+(15)/(100)* 82.89`

`82.89+0.15* 82.89`

`82.89+12.43`

`95.32`

The cost after the tip is $95.32.

Therefore, the total cost is $95.32.
