Problema Solution
There is a sales tax of 8$ on an item that costs $82 before tax. A second item costs $123 before tax. What is the sales tax on the second item?

First we will find the sales tax.
The sales tax will be the same percent rate for both items.
Let p = the sales tax
p*82 = 8 divide both sides by 8
p = 8/82
p = 4/41
p = 4/41 of the second item's cost gives:
(4/41)*123 = 4*3 = $12
the sales tax on the second item is $12.
