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.
[tex]\text{Decrease percent}=\frac{|\text{Final}-\text{Initial}|}{\text{Initial}}\times 100\%[/tex]
[tex]\text{Decrease percent}=\frac{|38.88-40|}{40}\times 100\%[/tex]
[tex]\text{Decrease percent}=\frac{|-1.12|}{4}\times 10\%[/tex]
[tex]\text{Decrease percent}=\frac{1.12}{4}\times 10\%[/tex]
[tex]\text{Decrease percent}=0.28\times 10[/tex]
[tex]\text{Decrease percent}=2.8\%[/tex]
Therefore, the percent decrease from Target's price to Sam's Club's price is 2.8%.
