Answer: Income will increase by $16 per unit
Explanation:
Your question isn't complete but the completed question was gotten online and would be used in answering the question accordingly.
The effect on income if Derby decides to make the motors will be calculated thus:
In-house:
Direct material = 38
Direct labor = 50
Overhead (Incremental) = 21
Total variable cost = 109
Outside:
Cost of supply = 125
Therefore, the income per unit will increase by (125 - 109) = 16.

Answer: a. 10 utils
Explanation: The marginal utility from consumption of the third unit of goods is gotten by taking the difference between the total utility derived from three units of goods and the total utility derived from two units of goods.
Total utility from three units = 84 utils
Total utility from two units = 74 utils
84 - 74 = 10 utils which is the marginal utility of the third unit.
Answer:
E) -2.50 ; inferior
Explanation:
Before you earned $3,500 per month, you consumed 7 units per month. That means that you consumed 1 unit every $500 earned.
When your income increased to $4,000, you only consumed 5 units per month. That means that your consumption decreased to 1 unit for every $800.
The income elasticity of demand using the midpoint method is calculated by using the following formula:
income elasticity = {change in quantity demanded / [(old quantity + new quantity) / 2]} / {change in income / [(old income + new income) / 2]}
= {-2 / [(7 + 5) / 2]} / {500 / [(3,500 + 4,000) / 2]} = (-2 / 6) / (500 / 3,750) = -0.333 / 0.133 = -2.5
Since the income elasticity of demand is negative, the good X is an inferior good.
