Answer:
the amount of C required is 190 units of C
Explanation:
the amount of C to cover the necessity of product A is
Ca = A units required * number of C units to manufacture a unit of A
Ca = 30 unit of A * 3 units of C/ unit of A =90 units of C
to produce B the same applies
Cb = B units required * number of C units to manufacture a unit of B
Cb = 25 unit of B * 4 units of C/ unit of B =100 units of C
therefore to cover the necessities of A and also B we will need:
total units of C required = units of C to produce A + units of C to produce B
C = Ca + Cb = 90 units of C + 100 units of C = 190 units of C
C= 190 units of C
