A printer that costs x
dollars is discounted by 40%
of the original price. There is an 8%
sales tax on the final price.

What TWO equivalent expressions show the final price of the printer and correct explanations?

A
1.08(x−0.40x)
because the sales tax is multiplied by the original price and then the amount of the discount is subtracted.
B
1.08(x−0.40x)
because the sales tax is multiplied by the final price after the discount.
C
x−0.432x
because the original price with sales tax is subtracted from the amount of the discounted price with sales tax.
D
1.08x−0.40x
because the sales tax is multiplied by the original price and then the amount of the discount is subtracted.
E
1.08x−0.432x
because the original price with sales tax is subtracted from the amount of the discounted price with sales tax.
