In some states, you pay a sales tax on items you purchase. A sales tax is a percent of what a customer pays for an item that costs c dollars. The expression 0.07(c – 0.05c) represents the amount of sales tax in a certain state that would be collected on an item that has been discounted by a certain percent. The expression has two factors.
What is the sales tax percent?

Best ResponseYou've already chosen the best response.3The item cost c originally. It had a discount of 5%. 5% = 0.05, so a discount of 5% means a discount of 5%c = 0.05c dollars That means that c  0.05c is the price of the item after discount but before tax. Which other factor do you still see? That must be the tax.

Best ResponseYou've already chosen the best response.3Correct. Now think of what 0.07 is doing there. The price of the item after discount is c  0.05c When you multiply 0.07 by c  0.05c, as in 0.07(c  0.05c), it's the same as taking 7% of the discounted price. What can you conclude is the tax in percent?
