Question

The swimsuit is on sale for 25% off its original price. If the original price was $58. What is the sale price?

Answer 1

$43.50

Explanation:

We can create a proportion to find the sale on the original price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. It is marked down by 25% so we pay 75% of the original $58.

`(75)/(100) =(x)/(58)`

We begin solving by cross multiplying numerator to denominator of each fraction.

`75(58)=100(x)\\4350=100x\\(4350)/(100)=(100x)/(100)  \\43.50=x`
