Question

What am I doing wrong here?

Answer 1

Answer:

$879.19

Step-by-step explanation:

I'm not sure how you got that, but here's what I did.

To calculate tax:

Cost before tax * Tax% = Tax

$815.95 * 7.75% = $63.24

To calculate cost after tax:

Tax + Cost before tax = Cost after tax

$63.24 + $815.95 = $879.19

Answer 2

Answer:

The answer is 879.1

Step-by-step explanation:

The original cost is $ 815.95

The cost rate is 7.75 %

The cost on the original cost will be 815.95 * 7.75/100 which comes out to be 63.23

So after adding the tax which is 63.23 to the original cost gives us 815.95 + 63.23 = 879.1
