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.

y − 0.15y
0.05(0.85y)
y − 0.85y + 0.05y
1.05(0.85y)

Answer 2

15% means you are paying 85% of the price.

Convert 85% to a decimal and multiply it by y <==== earlier step

When you apply tax to a item you are paying 100% of the item plus the sales tax.

In this example 100% + 5% = 105%, this must also be converted to a decimal and multiplied by the product in the earlier step.
