Mr. Purle is putting together bags of supplies to pass out to the teachers at the beginning of the school year. Each bag will contain the supplies shown in the table.

Question

A table shows items for bags of supplies. There are 26 number 2 pencils in the bag, there are 14 red pens in the bag, and there are 52 erasers in the bag.

Part A
Write two equations to find the total number of items in each bag. Use the Associative Property of Addition to write the two equations.

Answer 1

Let's call the total number of items in each bag "T".

Using the associative property of addition, we can combine the number of each item in the bag into one equation:

T = 26 + 14 + 52

Alternatively, we can break it down into two equations:

T = (26 + 14) + 52

T = 40 + 52
