HELP I NEED HELP WITH 1,2 and 8

Mathematics
1 answer:
Yanka [14]3 years ago
7 0

Answer:

$19.79

Step-by-step explanation:

The only problem provided is #8, so I will help on that one lolz.

First, you find 10% of $19.99.

That is $2

This is a discount, so subtract 2 from the original, 19.99.

You get 17.99.

Adding a sales tax of 10% is $1.80.

This makes $19.79
