Question

The price of a certain item is P dollars. The sales tax on the item is 7%. which expression represent the total cost of the item, in dollars, after the tax has been applied?​

Answer 1

1.07p or p + 0.7p

Explanation:

The price of any item plus 7% tax can be found by writing an expression. You can write an expression using a variable p where p is the price. You will pay the 100% the whole price and add on 7% of the price as tax. This means you pay 100 + 7 = 107% of the price p. This is 1.07p. Or you can also write it as p + 0.07p.
