Answer:
None of these is correct
Explanation:
The substitution effects is the decrease in sales for a product that can be attributed to consumers switching to cheaper alternatives when its price rises. The substitution effect is based on the idea that as prices rise, consumers will replace more expensive items with cheaper substitutions or alternatives, assuming income remains the same.
Answer:
The answer is: False
Explanation:
a product can sell if the price is higher or lower than its perceived value, take a market crash for example, many stocks are priced lower than its perceived value but some investors still buy it, or overpriced stocks, people that believe the stock will continue to go up would most likely buy it.
Answer:
(a)Total Cost, C=20LW+12LH+12WH
(b)
(c)W=1.88ft, L=5.64 ft and H=4.72 ft.

Explanation:
Given the dimensions of the box to be L,W and H.
(a)
- The material for the top and bottom of the box cost $10 per square foot
- The material used to build the four sides of the box cost $6 per square foot.
- Area of Top and Bottom=2LW
- Cost of Top and bottom=$10 X 2LW=20LW
- Area of four Sides =2(LH+WH)
- Cost of Four Sides =$6*2(LH+WH)=12(LH+WH)
- Total Cost, C=20LW+12LH+12WH
(b)The bottom side has length 3 times its width.
L=3W
Volume of the box=50 cubic feet.


Substituting L=3W and
into the cost function C.
C=20LW+12LH+12WH

(c)The minimum cost occurs at the point where the derivative of the cost function equals zero.

Recall:

The dimensions of the box that minimize the cost are W=1.88ft, L=5.64 ft and H=4.72 ft.
Cost of the box at these dimension
