Wren bought a baseball card last year for $2.25. This year the price dropped to $.45. What was the percent of decrease in the price of the card

A. 120%
B. 500%
C. 80%
D. 400%

A?

2.25 divided into .45 = 5 times 100 = 500 %

To calculate the percent of decrease, we need to find the difference between the initial price and the final price, and then divide that difference by the initial price. Finally, we multiply that result by 100 to get the percentage.

The initial price of the card was $2.25, and the final price is $0.45. To find the difference, we subtract the final price from the initial price:

$2.25 - $0.45 = $1.80

Next, we divide the difference by the initial price:

$1.80 / $2.25 = 0.8

Finally, we multiply the result by 100 to get the percentage:

0.8 × 100 = 80%

Therefore, the correct answer is C. 80%.
