What is the percent increase in value of the baseball card?
About 26.33%
About 33.33%
About 55.67%
About 66.67%

Answer 1

To calculate the percent increase in value of the baseball card, you can use the formula:

\[
\text{Percent Increase} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100\%
\]

Given:
- Old Value = $39
- New Value = $65

Now, substitute the values into the formula:

\[
\text{Percent Increase} = \frac{65 - 39}{39} \times 100\%
\]

Calculating the difference:

\[
65 - 39 = 26
\]

Now, plug it back into the formula:

\[
\text{Percent Increase} = \frac{26}{39} \times 100\%
\]

Calculating \(\frac{26}{39}\):

\[
\frac{26}{39} \approx 0.6667
\]

Now multiply by 100 to get the percentage:

\[
0.6667 \times 100\% \approx 66.67\%
\]

So, the percent increase in value of the baseball card is **about 66.67%**.
