Question

please help me im confused.

Every item in the Just a Dollar store is priced at $1.00. When Mary Jo opens the store, there is $122.00 in the cash register. When she counts the money in the cash register at the end of the day, the total is $1,065.95. If the sales tax rate is 8.5%, how many items were sold that day?

Answer 1

Hmm..

Let's break this down with what is given.

There is a total of 1065.95 total.

Mary has 122 in the cash register initially.

So subtract
1065.95 - 122 = 943.95

943.95 is the total items she sold including tax

Let's Figure out that amount excluding the tax, which is what the question is asking.

943.95*.085 = 80.24

80.25 is what the total tax is

943.95-80.24 = 863.71

So she old 864.71 items.
