Problema Solution
an elevator at a construction site has a maximum capacity of 2800 pounds if the elevator operator weighs 265 pounds and each cement bag weighs 65 pounds how many bags of cement can be safely lifted on the elevator in one trip?
solve algebraically
Answer provided by our tutors
let 'x' be the number of bags of cement that can be safely lifted in one trip
the total weight must be not more then the maximum capacity of 2800 pounds thus we have
265 + 65x <= 2800
x <= (2800 - 265)/65
x <= 39
this means that not more then 39 bags of cement can be safely lifted on the elevator in one trip.
