The expression 0.07x+(x−300) models the final price of a television set with an instant rebate in a state that charges a sales tax. The sales tax is on the original price.

Which expression represents the price of the television set after the instant rebate is applied but before the tax is applied?

a.) 0.07x-300
b.) x-300
c.) 1.07x
d.) 0.07x

Answer 1

The instant rebate normally is something we need to reduce, so I guess 300 is that amount, so a tax on the original price should be 0.07x, and the original price is x, so the price after the instant rebate should be x-300 before the tax is applied, I will choose b).
