Answer:
$91
Step-by-step explanation:
To find 20% off of $120 set it up as a fraction.
We are trying to find x.
x/120 = 20/100
Now you are going to cross multiply to get the unchanged/non-simplified version of you soon to be answer.
2400/100x
Simplify that to find how much you need to subtract from $120 when the discount is added. 2400/100 = 24. 120-24 = 96. Then subtract 5 from 96 and that will give you your final answer.
