Answer:

total savings using CFL light bulbs = $47.09

Explanation:

We can compare the costs of 8,000 hours of lighting:

incandescent light  bulbs

  • you need 8 incandescent light bulbs to generate 8,000 hours of lighting = 8 x $0.70 = $5.60
  • they will consume a total of 150 watts x 8,000 hours = 1,200 kWh x $0.05 per kWh = $60
  • total cost = $5.60 + $60 = $65.60

CFL light bulbs

  • you need one CFL light bulb to generate 8,000 hours of lighting = $5.71
  • it will consume a total of 32 watts x 8,000 = 256 kWh x $0.05 = $12.80
  • total cost = $5.71 + $12.80 = $18.51

total savings = $18.51 - $65.60 = -$47.09

C = 50 + 0.8Y is the consumption function that is consistent with the provided data. The MPC is determined by subtracting the change in consumption from the change in disposable income, which equals 160/200, or 0.8.

Marginal propensity calculation.

$200 billion less $0 billion equals $200 billion in changes to disposable income.

Consumption change equals $210 minus $50, or $160 billion.

MPC = Change in Consumption/Change in Disposable Income, which equals $160 billion/$200 billion and is equal to 0.8.

There is a 0.8 marginal tendency to consume.

Step 2

This is how consumption function is defined.

C = a + bY

Where,

a = Consumption at zero income level

b = MPC

In given case,

$50 billion would be consumed at a level of income zero.

MPC is 0.8

So,

C = 50 + 0.8Y is the consumption function that matches the provided data.

What did u learn about entrepreneurial activities​
natta225 [31]
Entrepreneurship is a quality that is very attractive to colleges. Admissions committees like to see that you can think outside the box, be creative, and make opportunities for yourself. It’s a skill that’s particularly relevant right now: Many products and services you use came from startups or from companies that began that way.

Bengal Co. provides the following sales forecast for the next three months: July August September Sales units 5,000 5,700 5,560
nydimaria [60]

Answer:

Total production= 5,840 units

Explanation:

Giving the following information:

Sales in units:

July= 5,000

August= 5,700

September= 5,560

The company wants to end each month with ending finished goods inventory equal to 25% of the next month's sales. The finished goods inventory on June 30 is 1,250 units.

To determine the production for August, we need to use the following structure:

Production budget:

Sales= 5,700

Desired ending inventory= (5,560*0.25)= 1,390

Beginning inventory= (1,250)

Total production= 5,840 units
