Answer:
Make no change in Y and Z.
Explanation:
It was assumed that consumer purchases the combination of two goods, Y and Z.
[tex]\frac{MU_{Y} }{P_{Y}}= \frac{30}{2} = 15[/tex]
[tex]\frac{MU_{Z}}{P_{Z}}=\frac{45}{3}=15[/tex]
For maximizing the utility of the consumer, the ratio of marginal utilities must be equal to the price ratio of the products.
We can see that the ratio of marginal utilities is equal to the price ratio of the products. Hence, the consumer should not make any changes to the combination of products.
