The value of an autographed baseball card increased from $39 to $65. What is the percent increase in value of the baseball card? Round to the nearest hundredth of a percent

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%
