Question

An appliance store decreases the price of a​ 19-in. television set ​28% to a sale price of $455.76 What was the original​ price?

Answer 1

• $633.00

Explanation:

Let the initial price be x.

We have:

• Decrease rate = 28%,
• Sale price = $455.76

The price has decreased from x by 28% and become $455.76.

Set equation and solve for x:

• x - 28% of x = 455.76
• x - 28x/100 = 455.76
• x - 0.28x = 455.76
• 0.72x = 455.76
• x = 455.76/0.72
• x = 633
