2. The value of an autographed baseball card increased from \( \$ 39 \) to \( \$ 65 \). What is the percent increase in value of the baseball card, to the nearest percent?

To determine the percent increase in value, you start by calculating the difference in value. Subtract the original value from the new value: \( 65 - 39 = 26 \). Next, you divide this difference by the original value: \( \frac{26}{39} \). Finally, multiply by 100 to convert it to a percentage: \( \left( \frac{26}{39} \times 100 \right) \approx 66.67 \). Rounding this to the nearest percent, the percent increase in value is approximately \( 67\% \). This simple math problem demonstrates how valuable collectibles can appreciate over time! The thrill of buying or trading sports memorabilia doesn't just hinge on passion; savvy collectors keep a keen eye on market trends and values to gauge their investments' worth. Whether it's a baseball card, a rare comic, or a vintage toy, knowing how to calculate increases in value can make you a smarter collector!
