Answer:
D. The demand curve shifts to the right.
Step-by-step explanation:
Movie tickets and film streaming services are substitutes, so an increase in the price of film streaming will cause an increase in the demand for movie tickets. Thus, at any given price, the demand curve of movie tickets shifts to the right, for example from demand A to demand B or demand C. as in the attached figure.
Using the given equation and edge length:
V = 45^3
V = 45 x 45 x 45
V = 91,125 cubic meters
Counting each visible cube, and multiplying it by 2, he used 112. If you counted them, there would be 56 cubes. You'd multiply by 2 for the non-visible ones.
