Target sells a pack of iTunes gift cards for $40. Sam's Club sells them for $38.88. What is the percent decrease from Target's p

patriot [66]

We have been given that target sells a pack of iTunes gift cards for $40. Sam's Club sells them for $38.88. We are asked to find the percent decrease from Target's price to Sam's Club's price.

We will use percent decrease formula to solve our given problem.

$\text{Decrease percent}=\frac{|\text{Final}-\text{Initial}|}{\text{Initial}}\times 100\%$

$\text{Decrease percent}=\frac{|38.88-40|}{40}\times 100\%$

$\text{Decrease percent}=\frac{|-1.12|}{4}\times 10\%$

$\text{Decrease percent}=\frac{1.12}{4}\times 10\%$

$\text{Decrease percent}=0.28\times 10$

$\text{Decrease percent}=2.8\%$

Therefore, the percent decrease from Target's price to Sam's Club's price is 2.8%.
