The value of a jewel in 2015 was $17500. The jewel was purchased in 2008, and its value appreciated 2.5%
ArbitrLikvidat [17]

Answer:

$14722.14

Step-by-step explanation:

We are given that

In 2015

The value of jewel=$17500

Rate of appreciation, r=2.5%

We have to find the initial value of the jewel when it was first bought.

Time, n=7 years

Final value=Initial\;value (r/100+1)^n

Using the formula

17500=Initial\;value(2.5/100+1)^7

17500=Initial\;value(1.025)^7

Initial\;value=\frac{17500}{(1.025)^7}

Initial value=$14722.14

Hence, the the initial value of the jewel when it was first bought=$14722.14

The stadium has 9400 seats. 7990 of these seats are in the sun today. What percent of seats are NOT In the sun?
AURORKA [14]

Answer:

15%

Step-by-step explanation:

When looking at the problem, you are given the total number of seats and the number of seats that are in the sun. There are two ways that you can go about this problem

1) In this method, you want to find how many seats are not in the sun. First you would take the total number of seats (9400) minus the number of seats in the sun (7990) to find the amount of seats not in the sun. 9400 - 7990 = 1410 seats. After this, you simply want to find the percentage by doing the part over the whole multiplied by 100 and it would look like this: (1410 / 9400) * (100) = 15%

2) You can find the percentage of seats in the sun and you know that it's compliment is the seats out of the sun. So it would look similar to the last one by doing part over whole multiplied by 100: (7990 / 9400) * (100) = 85% in the sun. Then you would subtract that from 100%: 100 - 85 = 15% of seats not in the sun.

I hope that this helps!

14 ) Mark Achin sells 3,600 electric motors each year . The cost of these is $ 200 each , and demand is constant throughout the
ANTONII [103]

Mark Achin's economic order quantity in units is <u>D. 120​ units</u>.

<h3>What is economic order quantity?</h3>

The economic order quantity (EOQ) is the optimal order quantity that minimizes the total costs (ordering, receiving, and holding inventory).

The formula for the economic order quantity is the square root of [2(setup costs)(demand rate)] / holding costs.

<h3>Data and Calculations:</h3>

Annual demand = 3,600

Cost price per unit = $200

Ordering cost = $40

Holding cost per unit = $20

Working days per year = 360

Lead time = 5 days

Economic order quantity (EOQ) = square root of: [2(setup costs)(demand rate)] / holding costs.

= square root of (2 x $40 x 3,600)/$20

= 120

Thus, Mark Achin's economic order quantity in units is <u>D. 120​ units</u>.
