Please Check My answer 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? 0.0035 is my answer

    The 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.

    0.07 is the other factor I see, is that what you mean?

    Correct. 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?

    0.07(c - 0.05c), it's the same as taking 7% of the discounted price The answer is that the tax is 7%

    Thank You, I thought that you have to multiply 0.07(c-0.05c)
