The counter on a business copier read 18,678 at the beginning of the week and read 20,438 at the end of the week. if the business was in operation 40 hours that week, what was the average number of copies made each hour.

Start with how many copies were made in that week. (You would find that by subtracting the beginning number from the end number ) then since you want copies PER hour, you would want to divide your new number of copies by the number of hours the business was open that week.

Be sure to label your number answer with copies per hour!
