Question

You just bought a new laptop and paid an initial payment of $150.00. You will make 12 payments of $69.50. How much will the computer cost if your state charges 6% sales tax on the total sale.

Answer 1

Using proportions, it is found that the computer will cost $1,043.04.

What is a proportion?

A proportion is a fraction of total amount.

In this problem, the total amount is composed by:

• An initial payment of $150.

• 12 payments of $69.50.

• 6% sales tax, which means that the price is increased by 6%, that is, the previous amount is multiplied by 1.06.

Hence, the cost is given by:

C = 1.06 x (150 + 12 x 69.50) = 1043.04.

The computer will cost $1,043.04.
