Final answer:
The first child's savings account had a greater percent of increase with 66.67%, compared to -83.33% for the second child's account.
Step-by-step explanation:
In order to determine which savings account had a greater percent of increase, we need to calculate the percent increase for each account. Percent increase is calculated by subtracting the original amount from the final amount, dividing that result by the original amount, and then multiplying by 100. Let's calculate the percent increase for each account:
For the first child's account:
Percent increase = ((Final amount - Original amount) / Original amount) * 100
= (($500 - $300) / $300) * 100
= (200 / 300) * 100
= (0.6667) * 100
= 66.67%
For the second child's account:
Percent increase = ((Final amount - Original amount) / Original amount) * 100
= (($50 - $300) / $300) * 100
= (-$250 / $300) * 100
= (-0.8333) * 100
= -83.33%
Therefore, the first child's savings account had a greater percent of increase, with 66.67% compared to -83.33% for the second child's account.
