Jenson has been working a summer job and putting his earnings into a savings account. At the beginning of the summer Jenson had $798 in his savings account and $3,214 at the end of the summer. What is the approximate percent increase for the amount of money in his savings account?

To calculate the percent increase, you need to find the difference between the final amount and the initial amount, then divide that by the initial amount and multiply by 100 to get the percentage.

Final amount - Initial amount = $3,214 - $798 = $2,416

Percent increase = ($2,416 / $798) * 100 ≈ 303.00%

Therefore, the approximate percent increase for the amount of money in Jenson's savings account is approximately 303.00%.
