To find out how many pears were in the box, we need to add together the number of pears that Mary and Carmie ate. Mary ate 412 pears, and Carmie ate 724 pears. So, to find the total number of pears, we can add these two numbers together: 412 + 724 = 1136. Therefore, there were 1136 pears in the box.
