Answer:
The correct answer is option A.
Explanation:
Sharon in consuming two goods X and Y.
The price of X is $2 and that of Y is $1.
The marginal utility derived from consuming X is 60 utils and from consuming Y is 30 utils.
For profit-maximization the ratio of marginal utility and price should be equal for both goods or the marginal utility of money spent on both goods should be equal.
The ratio for good X
= 
= 
= 30
The ratio for good Y
= 
= 
= 30
Since the ratio is same for both the goods it implies that Sharon is maximizing her total utility.
X = 10.71 rounded to the hundredth
To get the break-even point, the Total Cost must equal to
the Total Revenue or Profit. The Total Cost is the sum of Fixed Costs and
Incremental Costs. Fixed costs are depreciation, advertising and insurance which
is equal to $5,871 per month. Incremental Costs are weed and feed materials,
direct labor, and fuel which is equal to $32 per lawn. The Marginal Revenue is
equal to $89 per lawn. Letting “N” to be the break-even point in number of
lawns, the break-even equation becomes: $5,871 + $32N = $89N. Then calculating
N, the break-even number of lawns is equal to 103.
