Answer:
A) is maximizing her total utility from the given fixed budget.
Step-by-step explanation:
The equal marginal principle refers to the principle in which the consumer would select that combination of goods which maximise its total utility. It could be selected by having marginal utility and its price
And for profit maximization, the marginal utility and the price is equivalent to both the goods.
i.e
30 = 30
Hence, the correct option is a.
