Answer:
D) 42.16
Total: $553.13
Step-by-step explanation:
Multiply the subtotal, 510.97, by 8.25%. To do that just turn the 8.25% into a decimal which is 0.0825. The answer to that would be 42.155025 and rounded it would be 42.16 so the tax would be $42.16.
The total to the entire thing would be $553.13 since you just add the tax and subtotal together.
Make use of the known limit,

We have

since
, and the limit of a product is the same as the product of limits.
is continuous at
, and
. The remaining limit is also 1, since

so the overall limit is 1.
