Hello and Good Morning/Afternoon:
Let's take this problem step-by-step:
If David buys the shirt online:
[tex]\hookrightarrow \text{he gets a 25 percent discount of the list price}[/tex]
[tex]\hookrightarrow \text{he pays for 75 percent of list price}[/tex]
If David buys the shirt in-store:
[tex]\hookrightarrow \text {he pays for 80 percent of the list price}[/tex]
[tex]\hookrightarrow \text{he gets a 5 percent discount of the store's price}[/tex]
[tex]\hookrightarrow \text{he pays 95 percent of the store price}[/tex]
[tex]\hookrightarrow \text{he pays '0.95 * 80' = 76 percent of the price}[/tex]
Thus David saves 1% if he buys the shirt online as compared to if he buys the shirt in-store.
Answer: (G) or 1%
Hope that helps!
