A baseball card decreased in value 25% in its first year and 10% in its second year. What was the total percent decrease of the card's value over the two years?
Answer/Solution
32.5%
Steps/Work
Let the initial value of baseball card = 100
After first year , value of baseball card = (1- 25/100)* 100 = 75
After second year , value of baseball card =(1 - 10/100)* 75 = 67.5
total percent decrease of the card's value over the two years = (100-67.5)/100 *100%
=31.5%
Answer C
After first year , value of baseball card = (1- 25/100)* 100 = 75
After second year , value of baseball card =(1 - 10/100)* 75 = 67.5
total percent decrease of the card's value over the two years = (100-67.5)/100 *100%
