Keith bought a pair of jeans at a discounted price of $91.00. The original price of the pair of jeans was $130.00. If Keith got the same discount on a t-shirt that originally cost $23.00, what is the discounted price of the t-shirt?

The discounted price of the t-shirt is $16.10.

Step-by-step explanation:

First find the percentage of the discount.

$130.00 (original price of jeans) - $91.00 (discounted price of jeans) = 39

Divide the difference in prices by the original price

39/130 = 0.3

Multiply by 100 for the percentage: 0.3 x 100 = 30%

Calculate 30% discount on the t-shirt price of $23.00

23 x. 3 = 6.9

Subtract discount from original price of t-shirt

$23.00 - $6.90 = $16.10

So first step would be to find the percent Keith got off for his jeans. To do that subtract 130-91 to get a difference of 39, then multiply 39 by 100 which is 3,900 and then divide by 130 which will give you 30. Which means Keith got 30% off his jeans. So, to find how much his shirt cost if he got 30% off you would multiply the original price, 23 by 0.3 or 30 percent and you get 6.9 then subtract 23-6.9 to get 16.1. So Keith bought his shirt for $16.10.
