Answer 2

Answer: 17$

Explanation:

There is a sales tax of $5 on an item costing $51 before tax.

So the ratio of sales tax to price before tax is the following.

$5 sales tax

$51 price before tax

A second item costs $173.40 before tax.

We have to find the sales tax, which we call Q. So we use the following proportion.

$5 sales tax = $Q sales tax

$51 price before tax $173.40 price before tax

Another way

Using the method of cross products, we solve for Q.

551 = Q173.40

51Q = ·5173.40

Q = ·5173.4051

Q = 17
