Homework Help: Algebra

Posted by Chelsea on Wednesday, January 27, 2010 at 7:04pm.

Every item in the Just a Dollar store is priced at $1.00. When Mary Jo opens the store, there is $128.50 in the cash register. When she counts the money in the cash register at the end of the day, the total is $1023.10. If the sales tax rate is 6.5%, how many items were sold that day?

Can someone please help me with this problem. I never know how to set these problems up.
