Answer:
A : $67.60
Step-by-step explanation:
Given:
Sales tax = 4%
She just bought a swimsuit whose full price was $80,
She presented the retailer with a coupon for $15,
Question asked:
What was the total amount that Elaine paid?
Cost price of swimsuit = $80,
She presented the retailer with a coupon for = $15,
Remaining price = 80 - 15 = 65
Now, sale tax imposed = 4% of 65
= ![\frac{4}{100} \times65 = \frac{ 260}{100} = 2.6](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B100%7D%20%5Ctimes65%20%3D%20%5Cfrac%7B%20260%7D%7B100%7D%20%20%3D%202.6)
Sale price = Remaining price after deducting coupon + sale tax
= 65 + 2.60 = 67.60
Thus , $67.60 Elaine paid to the retailer.
