By finding the percentage of interest for next month, we conclude that next month's interest charge will be $90.72

About how much will the next month's interest charge be?

There is an interest of 21% annually, and we can assume that we can decompose this on the 12 months.

Then on each month, the interest is:

21%/12 = 1.75%

So if he owes $5.184, an interest of 1.75% is:

I = (1.75%/100%)*$5.184 = $90.72

The next month's interest charge will be $90.72.
