Lower Elementary: 

 

 

Question: One robot can lift and carry 900 pounds. A second robot can lift and carry 1,800 pounds. If the robots work together, can they lift a boulder that weights 2,500 pounds?

 

 

 

 

Answer: Yes

 

 

 

Solution: Together, the robots can lift 900 + 1,800 = 2,700 pounds. Since 2,500 pounds is less than 2,700 pounds, the robots can lift the boulder.
