The answer is A. 
80%
I hope this helps! :) 

Answer:

a. 80%

Step-by-step explanation:

The percent of decrease can be calculated as:

[tex]Percentage Decrease = \frac{Initial price - Final Price}{ Initial Price}*100 [/tex]

Then, replacing initial price for $2.25 and final price for $.45 we get:

[tex]Percentage Decrease = \frac{2.25 - 0.45}{2.25} *100[/tex]

percentage of decrease = 80%

Finally the percentage of decrease in the price of the card is 80%
