Answer:
Make no change in Y and Z.
Explanation:
It was assumed that consumer purchases the combination of two goods, Y and Z.


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.
Answer:
a.$4
Explanation:
initial price of fish dinner per piece was= $10
no. of fish dinner sold = 5
total initial revenue= 5*10= $50
new price of fish dinner = $9
and now six fish dinners are sold
new revenue= 6*9= $54
therefore the marginal revenue from the sixth dinner sold= 54-50= $4
hence option a is correct
Ending capital for the month = The month's beginning capital + Additional capital inflow for the month - additional capital outflow for the month
For example: if had $500 at the beginning of a month, you got a dividend of $100 during the month and also spend $50 on entertainment during the month, the ending capital would be 500 + 100 -50 = $550
If he sells the shares at 30 per unit, the equation would be:
30*26000=780000
If he lowers the price to 29 per unit and ups the demand by 1k, it would be:
29*27000=783000
The resulting change would net him an additional 3000 dollars, so your answer would be B.
