Question

A truck can at most be filled with 20 ton. If there are currently 14 ton goods there already, write an inequality representing the possible the weight of goods that can be added to the truck, then solve for the most amount of goods that could be added. ___ ton

Answer 1

`x + 14 \leq 20`, x = 6 ton

Explanation:

The truck can be filled with a total of 20 ton.

There are already 14 ton inside the truck, so if we call x the weight of goods that we can still add into the truck, we know that (x+14) must be equal at most at 20. Therefore, the inequality becomes:

`x+14\leq 20`

Solving it, we find

`x\leq 6`

which means that the most amount of goods that could be added to the truck is 6 tons.
