Answer:
$4.80
Step-by-step explanation:
First, apply the coupon to the original price
20% of 14.99 = 2.998
or
0.20 x 14.99 = 2.998
Then, find the sales tax of the new price
%6 of 2.998 = 1.7988
or
0.60 x 2.998 = 1.7988
Finally, add the sales tax to the new price
2.998 + 1.7988 = 4.7968
Round 4.7968 to the nearest tenth to get 4.80
