The value of an autographed baseball card increased from $39 to $65 what is the percent increase in value of the baseball card?

Ivan

The percent increase is found by finding the difference between the two prices and then dividing that different by the beginning price.

For this example it would be 65-39= $26. So $26/$39(the starting price) is 0.666... This is equivalent to about 66.67%. So, the price of the card increased by about 66.67%
