Question

Carson has a loyalty card good for a discount at his local pharmacy. The item he wants to buy is priced at $13, before discount and tax. After the discount, and before tax, the price is $12. 48. Find the percent discount.

Answer 1

4% discount

Explanation:

`P_o=` original price

`P_d=` discounted price

`P_d=(P_o)*(1-(P_o-P_d)/(P_o))`

We are given

`P_o=13.00`

`P_d=12.48`

We can use the equation below to find the percent discount

`D_p=(P_o-P_d)/(P_o)*100`

Substituting our numbers gives us

Let
`D_p` = percent discount

`D_p=(13-12.48)/(13)*100`

`D_p(0.52)/(13)*100`

`D_p=0.04*100`

`D_p=4`
