Answer 1

Answer:

Answer:

The total cost is $95.32.

Step-by-step 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.

Matt earned 28,500 last year. Paid 8,265 for rent. What percent did he pay for the rent

Answers

29%

If you put the amount he paid for rent (8,265) over the amount he earned (28,500), then you will get a decimal number.
8,265/28,500=.29
You then take this decimal and multiply by 100 to get the percent.
.29*100=29%
