A machine requires 4 hours to make a unit of Product A and 3 hours to make a unit of Product B. Last month the machine operated for 200 hours producing a total of 60 units. How many units of product A were produced?

[legendboy]

20 units of product A I think

Simple systems of equations, but this could be wrong ! haha

4x +3y = 200
x + y = 60

4(-y + 60) + 3y = 200
y = 40

then

4x +3(40) = 200
x = 20

x = product A
