Answer:
$130.01 is the fee charged.
Explanation:
We know that Arnold purchased the set of gold for $1300. However, he has to pay $158.89 per month for 9 months, the final cost would be
![158.89(9)=1430.01](https://img.qammunity.org/2020/formulas/mathematics/high-school/kh6b8aarl71yk9tuafjqsra4l59oymjhh4.png)
So, the difference with the initial amount would be:
![1430.01-1300=130.01](https://img.qammunity.org/2020/formulas/mathematics/high-school/yfwnmmj9gsm405o0qj0k3eylxmo12kfsrd.png)
Therefore, the layaway plan is charging a fee of $130.01.
