Greg built a plane model. The initial weight of Greg's model was 21.8 pounds. He added a propeller that weighed of the initial weight of the model. Greg estimates that the total
weight of the model with the propeller is about 24 pounds. Is Greg's estimate of the total
weight of the model reasonable?
