• Mrs.  Moore has 250 M&M's.  She has 80 red M&M's and 80 blue M&M's.  How many green M&M's does she have?

• Mrs. Moore bought 3 bags of M&M's.  Each bag had 80 M&M's inside.  How many bags would she needs to buy in order to have 250 M&M's?

• Mrs. Moore had 250 M&M's.  She gave her class 80 M&M's and her switch class $80 M&M's.  How many M&M's does she have left?

A factory makes 400 refrigerators every day. The factory makes 125 more stoves per day than refrigerators. Which equation can be used to find x, the total number of refrigerators and stoves the factory makes in one day?

• x = 400 + (400 + 125)

• x = 400 + 125

• x = 400 + (400 - 125)

• x = 400 - 125
