Question

There were 36 sweatshirts on sale for 2/3 of the regular price. What was

the sale price if the regular price was $30?

Answer 1

To sum up, we solved for W. Finally, the sale price of a sweatshirt was 20$.

Explanation:

So we have our main equation of W/G=p. The G stands for the total amount which is 30. The W is the unknown in this case. As for the p equals 2/3.

Thus we substitute G and p into the equation W/30=2/3. We multiply both sides of the equation with 30 W=2*30/3. Which gives us 60/3=20.
