Answer:
Trey has 60 more cents in commission ,if his commission is based on the original price of the coat.
Step-by-step explanation:
Commission received based on original price of $60 is 5% of $60=$3
While the commission applicable if the commission is based on the price of the coat after 20% discount is 80% of $60 *5%=$2.4
The difference between the two discount figures is $3-$2.4=$0.60
Hence Trey has 60 more cents if discount is computed using the former basis instead of the latter approach.
