Answer:

  • a) $56000
  • b) DA = 2, GA = 10

Step-by-step explanation:

Given

  • DA = A + B ⇒ $3000
  • GA = A + 2B ⇒ $5000
  • Number of A = 12
  • Number of B = 22

We can see from the equations that

  • GA - DA = B ⇒ $2000 and
  • A = $1000 and B = $2000 in terms of profit

So greater use of unit B brings greater profit. We don't want any unit is left over, so get this equation.

  • A + B = 12
  • A + 2B = 22

Is the equation set to indicate use of the units A and B

Solving we get

  • A = 2 and
  • B = 10

It this case all the units are used and profit is maximum

  • 2*$3000 + 10*$5000 = $56000
  • Number of DA = 2
  • Number of GA = 10
