A smart phone that sells for $259.99 is on sale for $199.99. Find the discount rate

Question

I don't know how to solve the problem

Answer 1

$199.99/$259.99 = $199.99 ÷ $259.99 ≅ 0.77, which means that the new price is about 77% of the original price, or a discount of (100 − 77)% = 23%.

Answer 2

When you subtract from the sale price from the original price, divide that difference by the original price, then multiply times 100, you get the discount rate.

 

So first, what is the difference in price? 259.99 - 199.99 = 60.00.

 

The discount rate = 100% * (60/259.99) = 23.1%
