Answer:
$23
Step-by-step explanation:
Original Price = 80
75% discount means we find 75% of 80 and then subtract it from 80.
75% = 75/100 = 0.75
0.75 * 80 = 60
So, after discount price = 80 - 60 = $20
On top of that is 15% sales tax. So let's find 15% of $20 and add it to it.
15% = 15/100 = 0.15
0.15 * 20 = $3
After tax price = 20 + 3 = $23
