mr_godi [17]

Answer:

She consumes 30 blue ray disk and 60 DVD respectively.

Step-by-step explanation:

Consider the provided information.

$U(x,y)=10x^2y$

Calculate marginal utility of good

Differentiate with respect of x and y.

$MU_x=20xy$

$MU_y=10x^2$

Her consumption of Blu-ray disks (X) with a price of $40 and Y is her consumption of DVDs with a price of $10.

The ratio of marginal utility of good x to y is equal to the price ratio:

$\frac{MU_x}{MU_y}=\frac{P_x}{P_y}$

Substitute the respective values.

$\frac{20xy}{10x^2}=\frac{40}{10}$

$\frac{2y}{x}=4$

$2y=4x$

$y=2x$

She has $1800 with which to spend on the two goods.

Her consumption of Blu-ray disks (X) with a price of $40 and Y is her consumption of DVDs with a price of $10. She has $1800 with which to spend on the two goods.

Therefore, $40x+10y=1800$

$4x+y=180$

Substitute the value of y in above equation.

$4x+2x=180$

$6x=180$

$x=30$

Thus, $y=60$

She consumes 30 blue ray disk and 60 DVD respectively.

2. a. A fish is 12 meters below the surface of the ocean. What is its elevation?

Alex17521 [72]

Answer:

A. -12 meters

B. 28 meters

C. 40 meters

Step-by-step explanation:

The surface of the ocean would be 0.

Taking this into account, 12 meters below would be 0 - 12, which is -12. Therefore A's elevation would be -12.

For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.

Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.
