Astore charges 7% sales tax. which expression can be used to find the total cost of an item with a price of p? 0.07p 0.93p 1.07p 7.00p

If you have an item that costs 10 dollars and a sales tax of 7% you could do it this way

10 * 7/100 = 0.70 dollars.

The total cost is 10.70 dollars. or 10 dollars and 70 cents.

The best way to do the total however is to multiply the cost by 1.07. You will get the number the customer has to pay.

10 * 1.07 = 10.70

So for any price (p) it would be 1.07*p

1.07p

Step-by-step explanation:

The tax  equals the price times the tax rate

We know the price p and the tax rate 7%

tax = p*7%

Changing this to decimal form

tax = .07p

The  final price of the item is the sales tax plus the price

final price = tax + price

                   .07p +p

                  1.07p

linear
