Extra Credit (5pts) A new pair of shoes is advertised for $75. The sales tax is 8.25%. What is the total cost of the shoes? (Give the answer and proportion please)

I'm here to help!

First, we need to make a proportion to find the sales tax:

(Let x= Sales tax)

We have the sales tax!

Now we need to estimate, as you cannot have.75 of a cent...

Now to add them:

There you go! The total cost is about 81.19!

Hope this helps!

P.S. Stay Safe!
