Question

Jamie purchased a DVD that was on sale for 15% off. The sales tax in her county is 5%. Let y represent the original price of the DVD. Write an expression that can be used to determine the final cost of the DVD.
A)0.05(0.85y)
B)y − 0.85y + 0.05y
C) 1.05(0.85y)

Answer 1

First you take the 15% off of the price, 'y', then you multiply 5% and add it to 'y'. The equation that matches that description would be B.

Answer 2

answer is C) 1.05(0.85y)

hope that helps
