Janet has $40. She gives $25 to Emma. What percent of Janet's money does Emma have?

0.625%
1.60%
55%
62.5%

To find the answer, you need to divide the amount given by Janet to Emma by the amount Janet had initially and multiply by 100 to get the percentage.

$25/$40 * 100 = 62.5%

Thus, Emma has 62.5% of Janet's money.
