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.

Assets are 300,000 and equity is 100,000, assets increase 80,000 liabilities increase 50,000. what is equity at year end?
mojhsa [17]
<span>Assets - equity = liabilities
  So liability before the increase is:
 300, 000 - 100, 000 = 200, 000
 And if assets increases by 80, 000. Hence new assets = 380, 000. Liabilities increases by 50, 000; hence new liability = 250, 000.
 New Equity = New Assets - New liability.
 New Equity = 380, 000 - 250, 000 = 130, 000.</span>

Jenny's bakery makes two types of birthday cakes: yellow cake, which sells for $25, and strawberry cake, which sells for $35. Bo
Marina86 [1]

Answer: Revenue is maximum at x=25 and y=0. That is when the firm makes only yellow cakes and no strawberry cakes.

Explanation:

x- Number of Yellow cakes

y- Number of Strawberry cakes

Time constrain is given by

2x+3y\leq 450

x\geq 0

y\geq 0

Revenue is given by,

TR= 25x + 35y

At the vertices, revenue is

At (0,0)

TR = $0

At (0,150)

TR = 25(0) + 35(150) = $5,250

At (225,0)

TR = 25(225) + 35(0) = $5,625

Therefore, Revenue is maximum at x=25 and y=0. That is when the firm makes only yellow cakes and no strawberry cakes.

Economic theory and the data in the table show that the average total cost curve and the marginal cost curve are related in that the MC curve passes through the minimum point of the ATC curve.

<h3>What is the relationship between the MC and ATC curves?</h3><h3 />

The data given by the table (which is accurately filled up) shows that the MC curve will intersect the ATC curve at its lowest point.

We see this from the fact that before the lowest ATC of 0.107, the marginal cost was less than the ATC. After the lowest ATC however, the marginal cost becomes higher than the ATC.

This shows that the MC curve intersected the ATC at its lowest point of 0.107 and then kept rising above it.
