Answer:
The retail price is $15.30
Step-by-step explanation:
To solve this, turn the percentage into a decimal. Do this by dividing it by 100.
180 ÷ 100 = 1.8
Then, multiply the supplier price by the decimal
8.5 × 1.8 = $15.30
She should get $44.59 back in change
3(6.75) + 4(8.79) = 20.25 + 35.16 = 55.41
100 - 55.41 = $44.59
That’s is actually right btw
