10.89+12.48=23.37
23.37*1.08=$25.24
He only charge tax on the 12.48.
12.48*1.08=13.48+10.89=24.37

He didn't calculate sales tax for both items, just one. He calculated sales tax for the second ring, then added the price of the first ring to that total. If he had calculated sales tax for both items, the total would be $25.24.

10.89 x 1 = (a)
12.48 x 1 = (b)
add them together = (c)
subtract your result from 24.37 = (d)
Divide (d) by (c) =
do you see it now?
