yards
and five and one-half yards of fabric is 
yards
Difference between five and one-half yards and Three and one-half yards is
=2 yards which is positive
Thus it clear that 
Answer:
it is the first one
Step-by-step explanation:
R(x) = 60x - 0.2x^2
The revenue is maximum when the derivative of R(x) = 0.
dR(x)/dx = 60 - 0.4x = 0
0.4x = 60
x = 60/0.4 = 150
Therefore, maximum revenue is 60(150) - 0.2(150)^2 = 9000 - 4500 = $4,500
Maximum revenue is $4,500 and the number of units is 150 units
