Given :

A morning truck can carry no more than 1480 pounds of cargo.

Brian loaded 640 pounds into the truck already.

He is loading boxes that weigh 70 pounds.

To Find :

How many boxes can he out into the truck.

Solution :

Weight left for carrying cargo, W = 4180 - 640 pounds

W = 3540 pounds

Number of boxes of 70 pounds cargo he can carry in truck is :

≈ 50 .

Therefore, number of box they can carry is 50.

Hence, this is the required solution.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
