Question

2.When I walked into King Soopers yesterday, I noticed that the Colorado Rockies t-shirts had a sign reading “25% off sale!”. If one shirt costs $20.99 with the sale, how much did the shirt cost before the sale?

Answer 1

Given:

The discount is 25%.

The selling price of the shirt after the sale is $20.99.

To find:

The selling price of the shirt before the sl;e

Step-by-step explanation:

Let the old price be x.

The equation can be framed as follows,

`\begin{gathered} ((100-25)/(100))* x=20.99 \\ (75)/(100)* x=20.99 \\ x=20.99*(100)/(75) \\ x=27.986 \\ x\approx27.99 \end{gathered}`

Final answer:

The selling price of the shirt before the sale is $27.99.
