Answer:
Mr. Thompson paid $56.16
Step-by-step explanation:
Given that the concert ticket Mr. Thompson purchased originally cost $78
Using a coupon code, he received a 20% discount.
20 % of $78 = 0.2 * $78
= $15.6
The disounted price is now
$78 - $15.6
= $62.4
The website applied a 10% service fee to the discounted price.
10% of $62.4 = 0.1 * $62.4
= $6.24
Final price is:
$62.4 - $6.24
= $56.16
