Answer:
The company will spend $200,000 more if they decide to manufacture the part internally.
Explanation:
Effect on cost if the company starts making the part can be expressed as;
Change in cost=Final cost-Initial cost
Final cost is the cost when Tom decides to produce the part internally which is 24 dollars per unit
Initial cost is the cost when Tom decides to pay for the part to be manufactured externally
where;
Initial cost=Cost per unit×number of units
Cost per unit=$20
number of units=50,000 units
Replacing;
Initial cost=(20×50,000)=$1,000,000
Final cost=Cost per unit×number of units
Cost per unit=$24
number of units=50,000 units
Replacing;
Initial cost=(24×50,000)=$1,200,000
Change in cost=Final cost-Initial cost
(1,200,000-1,000,000)=$200,000
The company will spend $200,000 more if they decide to manufacture the part internally.
