Every item in the Just a Dollar store is priced at $1.00. When Mary Jo opens the store, there is $127.00 in the cash register. When she counts the money in the cash register at the end of the day, the total is $1,055.80. If the sales tax rate is 8%, how many items were sold that day?

1,055.80 - 127.00 = 928.8

1.08 is dollar with 8% sales tax rate

928.8/1.08 = 860

So, 860 items were sold that day.

I hope this helps! :)

To find out how many items were sold that day, we need to determine the total amount of money that came from the sales. We can subtract the initial amount in the cash register from the final amount to get the total sales amount.

Total sales amount = Final amount - Initial amount
Total sales amount = $1,055.80 - $127.00
Total sales amount = $928.80

Since the sales tax rate is 8%, the total sales amount represents 100% + 8% of the actual sales amount. We can set up a proportion to find the actual sales amount.

Total sales amount / (100% + 8%) = Actual sales amount / 100%
$928.80 / 108% = Actual sales amount / 100%

To solve for the actual sales amount, we can cross-multiply and divide.

Actual sales amount = ($928.80 / 108%) * 100%
Actual sales amount = $860 * 100%
Actual sales amount = $860

Since every item is priced at $1, the number of items sold can be determined by dividing the actual sales amount by the price of each item.

Number of items sold = Actual sales amount / Price per item
Number of items sold = $860 / $1.00
Number of items sold = 860 items

Therefore, 860 items were sold that day.
