A company produces two types of drills, a corded and cordless. The cord-type drill requires 3 hours to make, and the cordless model requires 4 hours. The company has 720 work hours per day for manufacturing and daily storage of 190 drills per day.Let  = the number of cordless drills produced per day and  = the number of corded drills produced per day."Write the system of inequalities that represents the maximum number of drills that can be produced daily"

≤

≤

Answer 1

4x + 3y ≤ 720;

x + y ≤ 190;

x ≥ 0, y ≥ 0.

Max(x + y) ?

x = 150 and y = 40
