Answer:
Step-by-step 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
[tex]158.89(9)=1430.01[/tex]
So, the difference with the initial amount would be:
[tex]1430.01-1300=130.01[/tex]
Therefore, the layaway plan is charging a fee of $130.01.
