Question

( this is my summer math homework, please help!)

Answer 1

Using proportions, the selling prices are given as follows:

1. $46.92.

2. $15.29.

3. $17.16.

4. $20,280.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

To find the selling prices, we have to multiply the original prices by either 1.02(2% sales tax) or 1.04(4% sales tax), hence they are given as follows:

• 1. 46 x 1.02 = $46.92.

• 2. 14.99 x 1.02 = $15.29.

• 3. 16.50 x 1.04 = $17.16.

• 4. 19500 x 1.04 = $20,280.
