Question

For each hour of production, a certain factory requires 1 assembly line worker for every 25 units to be produced in that hour. The factory also requires 12 managers regardless of the number of units to be produced. Which of the following expressions represents the total number of assembly line workers and managers that this factory requires to produce 50N units in one hour, where N is a positive integer? (A)12 + 50N.(B)12 + 2N.(C)62N.(D)37N.(E)25N.

Answer 1

Answer:

(B)12 + 2N

Explanation:

If the company requires 1 assembly line worker for every 25 units in one hour, it will require 2 assembly line worker for every 50 units in one hour, and 2N assembly line worker for every 50N units in one hour, for every positive integer value of N.

As for the managers, the value stays constant at 12, regardless of he number of units to be produced.

Therefore, the number of workers (W) required to produce 50N units is:

$W(50N) = 12 +2N$
