Question 1171012: The weight of a cement truck on its way to a construction site is given by W= 1200 +50m, where W is the combined weight of the truck and its contents in Ibs and m is the weight of each cubic metre of cement.
The truck must pass over a bridge with a maximum weight of 10, 000Ibs.
To be cost effective, the truck needs to carry at least 100m^3 per trip
Determine the possible values for W and m in this situation.

You can put this solution on YOUR website! 10000 = 1200 + 50m
Solve to find m = 176, so the truck can carry 176 pounds maximum.
So, m can be any value from 100 to 176 and W can be any value from 6200 to 10000.

Excuse me,
as the problem is worded, printed, posted and presented, it is NONSENSICAL.
I do not solve problems, formulated in nonsensical way, in principle.
Also, I do not want to explain, WHY it is nonsensical.
It is not my job or my duty at this forum.
In opposite, it is the job and the responsibility of a visitor to provide a correct input.
