ermest works in the shipping department loading shipping crates with boxes. Each empty crate weighs 150 lb. How many boxes, each weighing 35 lb, can Ernest put in the crate if the total weight is to be no more then 850 lb?

Max weight of the crate - the empty crate/ by 35 (the weight of the individual boxes)

850-150=700

700 lbs is the remaining weight available that can be filled with 35 lb boxes, to find out the number of boxes that can be added to the crate, divide 700 by 35.

700/35 = 20

Ernest can put in 20 boxes in the crate.

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
