Answer:
-$28.8.
Explanation:
Note, we were told,
- to assume the cost of a therm is $0.30
- the family uses 600 therms of energy annually.
<u>Savings on old furnace:</u>
- 600 * $0.30 * 0.80 (or written as 80%) = $144
<u>Savings on new furnace:</u>
- 600 * $0.30 * 0.96 (or written as 96%) = $172.8
Difference: $144 - $172.8 = -$28.8.
Answer:
0.5
Explanation:
Zscore = (x - mean) / standard deviation
Given the data:
X : 462 490 350 294 574
The second observation = 490
The mean and standard deviation of the data could be obtained using a calculator :
Mean = 434
standard deviation = 112
ZSCORE = (490 - 434) / 112
ZSCORE = 56 / 112
ZSCORE = 0.5
I believe the correct answer is the first option. The labor supply curve is upward sloping because the opportunity cost of leisure decreases as wages decrease and the opposite of such is true as well. As one work one hour more, one will have less time for other activities. As the work rate increases in value, then the opportunity cost increases as well.
Answer:
The total cost of producing a given level of output is:____.
d. minimized when the ratio of marginal product to input price is equal for all inputs.
Explanation:
With the above situation, the marginal cost (input price) = the marginal revenue (marginal product). The producer can then maximize profit if it can lower its average total cost per unit below the marginal cost for producing one additional unit of its product. In all cost situations, it is better for the producer to have the total revenue exceeding the total costs, at all times, but more especially with increasing production.
