Answer:increased percent = 66.67%
Explanation:
The value of an autographed baseball card increased from 39$ to $65. This means that the price of the autographed baseball card increased from the original price to the new price by a certain percentage.
Let x percent = the percentage increase of the price of the autographed baseball card from the original price to the new price.
Percentage increase =
(New price of price of the autographed baseball card - the original price of the autographed baseball card) / the original price of the autographed baseball card × 100
From the information given,
New price of price of the autographed baseball card - the original price of the autographed baseball card = 65 - 39 = $26
Percentage increase = 26 / 39 × 100
= 66.67 %
