Caroline will need atleast 21 weeks to get a balance more than $100, or any number greater than 20 weeks.

Step-by-step explanation:

Caroline starts with $20 in her piggy bank. Each week she adds $4 to the piggy bank.

Let the number of weeks she adds $4 to make more than $100, be x.

Equation forms:

Solving for x;

=>

Dividing by 4 on both sides;

x > 20.

This means that Caroline will need atleast 21 weeks to get a balance more than $100, or any number greater than 20 weeks.
