Answer:
total cost would be about $19.07
Step-by-step explanation:
First you find out what 8 percent is from 15.50 which would be 1.24
Then you find out what 15 percent is from 15.50 which is 2.325 but you round it so it would be 2.33
Finally you add al three together, 15.50+ 1.24+2.33 which then sums up to the final cost
