Explanation:
If their father Dave allows them to trade chores to achieve gains from trade then "Henry will clean bath tubs; Rose will wash the windows".
<u>Option: C</u>
<u>Explanation:</u>
In this scenario Henry is washing 20 windows or 2 bath tabs in an hour, which showcase his average washing of 10 windows over 1 bath tab in half hour. While here Rose is washing 30 windows or 1 bath tab in an hour by giving average of 15 windows over half bath tab in half hour, which is less than Henry's average of washing.
Thus on considering the above average of work performed by Henry and Rose in equal amount of given time for work, Henry is more prominent to be specialized in cleaning bath tubs while Rose will more expert in washing windows because she is cleaning more windows than Henry in same on hour of time.
Profit will be maximum for the firm where marginal revenue = marginal cost.
Since, the market price is fixed at $8 and therefore each additional unit of camera will be sold at $8.
Hence, marginal revenue = $8.
From the table, it is clear that cameras are manufactured in batches of 100.
Marginal cost is the cost incurred to produce one additional unit of camera. It will be calculated by taking the difference of successive variable costs (or total costs) divided by 100.
To produce 400th unit, marginal cost = (2760 - 1960)/100 = $8
Hence, profit maximising quantity isB. 400 (MR = MC)
