A bridge can hold a maximum of 75,000 pounds. A truck that weighs 40,000 pounds carries boxes that weigh 40 pounds each. What is the maximum number of boxes the truck can carry to cross the bridge? Express your answer as an inequality.

Question

b≤

Answer 1

Let's denote the maximum number of boxes the truck can carry as "b".

The weight of the truck itself is 40,000 pounds, and each box weighs 40 pounds.

The weight of the truck and the boxes must not exceed the maximum weight the bridge can hold, which is 75,000 pounds.

Therefore, the inequality can be expressed as:

40,000 + 40b ≤ 75,000
