Assume you are in the business of producing and selling milkshakes. If you could produce more milkshakes with the same input, what would happen to your productivity and profits assuming the price of your milkshakes remains the same?

Both increases

Explanation:

Suppose a person initially produces and sell some amount of milkshakes with the available resources.

But, if he will be able to produce and sell more quantity of milkshakes with the same level of resources then this will indicates that there is a rise in the productivity of this person and if the number of milkshakes sold increases then as a result profits increases at a same price level.

For Example:

Case 1:

Initially,

Person producing and selling = 20 units of milkshakes at a selling price of $10 each and cost of inputs used in the production = $50

Therefore, Profits = Total revenue - Total cost

= (20 units * $10 each) - $50

= $200 - $50

= $150

Case 2:

Now, we assumed that there is an increase in the productivity of this person. Cost of production and selling price of each milkshake remains the same.

Person producing and selling = 40 units of milkshakes at a selling price of $10 each and cost of inputs used in the production = $50

Therefore, Profits = Total revenue - Total cost

= (40 units * $10 each) - $50

= $400 - $50

= $350

Hence, there is an increase in the profits from $150 to $350.
