The answer is “$553”.

Kelly’s account pays = 2.5 percent compounded daily = 2.5/100 = 0.025

There are 365 days in one year, so 

<span>
i = .025/365 </span>

so number of days = n = 4(365) = 1460 

Amount = 500(1 + .025/365)^1460 

<span>=552.59 = $553</span>

<span>The formula for calculating annual compound interest, including principal sum, is: A = P (1 + r/n)^(nt) Where: A = the future value of the investment P = the principal investment amout or the initial deposit r = the annual interest rate n = the number of times that interest is compounded per year t = the number of years the money is invested or borrowed. So we have that P = $500 r = 2.5% = 0.025, t = 4 years and n = 365 (since the interest is compounded daily). Plugging into the eqn we have A = 500 ( 1 + (0.025)/(365))^(365*4) A = $552.58</span>

sammy [17]

Answer:

-0.34

Explanation:

Given that,

Percentage increase in prices = 5%

Initial quantity demanded = 30,000

New quantity demanded = 2,500

By midpoint method,

Average quantity :

= (Initial quantity  + New quantity) ÷ 2

= (30,000 + 2,500) ÷ 2

= 16,250

Change in quantity = (2,500 - 30,000)

                                = -27,500

Therefore, the price elasticity of demand is as follows:

= (Change in demand ÷ Average quantity demanded) ÷ Percentage increase in prices

= (-27,500 ÷ 16,250) ÷ 5

= -1.69 ÷ 5

= -0.34

liraira [26]

Answer:

1. The correct category for each of the following items:

Cash In/Income:

Personal income

Business Income

Cash Out/Expense:

Cost of business trip = variable

State tax liability = fixed

Clothing purchases = variable

2. For example, your mortgage would be considered a fixed expense, because the total amount does not vary.  Conversely, grocery bills would be considered variable, because the actual amount is not fixed but varies.

Explanation:

Variable cost or expense has a fixed cost per unit, with the total amount varying, depending on the units or quantities consumed.  Fixed cost does have a fixed total amount within the relevant range, but the cost per unit varies.

dusya [7]

Answer:

C) 6 pounds of pork and 8 pounds of tomatoes

Explanation:

Explanation:

            Labor hours to make 1 lb. of:          lbs. produced in 24 hours

                 Pork                  Tomatoes              Pork            Tomatoes

Farmer         6                            3                       4                       8

Rancher       4                            4                       6                       6

If both decide to specialize in producing only one good, the farmer will produce 8 pounds of tomatoes per day and the rancher will produce 6 pounds of pork per day.

This way when the rancher trades 4 pounds of pork in exchange for 6 pounds of tomatoes, he is gaining 2 pounds of pork which is equivalent to 8 labor hours.

When the rancher trades 6 pounds of tomatoes in exchange for 4 pounds of pork, he is gaining 2 pounds of tomatoes which is equivalent to 6 labor hours.
