Question

You and your classmates create 18 watercolor paintings to sell at the PTA auction to raise money for your school. In order to pay for the materials you bought to make the watercolor paintings, you need to sell each of the watercolor paintings for $2.25. When transporting the watercolor paintings to the auction, one of your parents accidentally drops four of the watercolor paintings in the street and they are run over by a garbage truck. What is the new minimum price you need to set for the remaining watercolor paintings in order to pay for the materials?

Answer 1

Using proportions, it is found that the new minimum price you need to set for the remaining watercolor paintings in order to pay for the materials is of $2.89.

What is a proportion?

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

To pay for the materials, you need to sell 18 paintings at $2.25 each, hence the total is:

T = 18 x 2.25 = $40.5.

If you lose four paintings, you will sell 14, and still need to make $40.5, hence the price will be of:

P = $40.5/14 = $2.89.
