= (2,700 – 9[50])/3
= (2,700 – 450)/3
= 2,250/3 or 750
Answer: 750 chairs
Well that’s rather simple, don’t you think?
3(x) + 9(y) = 2700
now we plug in the 50 computer desks made
3(x) + 9(50) = 2700
3(x) + 450 = 2700
subtract
3(x) = 2250
they now have 2,250 hours, so let’s see how many chairs they can make in that time. Divide:
x = 750.
The company could make 750 chairs.
