Let
x = minutes used for jogging
y = minutes used for handball
z = minutes used for cycling
Th total time spent is 1 hour (60 minutes), therefore
x + y + z = 60
Because Mike jogs as long as he cycles, therefore
x = z
Therefore
2x + y = 60
or
y = 60 - 2x (1)
Jogging consumes 10 calories/min, handball consumes 9 calories/min and cycling consumes 12 calories/min.
The calories consumed in 60 minutes is 580, therefore
10 x + 9y + 12z = 580
Because x = z,
22x + 9y = 580 (2)
Substitute (1) into (2).
22x + 9(60 - 2x) = 580
22x + 540 - 18x = 580
4x = 40
x = 10
y = 60 - 2x = 40
z = x = 10
Answer:
10 minutes of jogging
40 minutes of handball
10 minutes of cycling.
Answer:
NPV = $-41,928.18
Explanation:
Net present value is the present value of after tax cash flows from an investment less the amount invested.
NPV can be calculated using a financial calculator:
Cash flow in year 0 = $-300,000
Cash flow each year from year 1 to 10 = $42,000
I = 10%
NPV = $-41,928.18
To find the NPV using a financial calacutor:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. After inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.
3. Press compute

Answer:
D. Cost of Goods Sold
Explanation:
The cost of goods sold or simply COGS is a numerical representation of the direct expenses incurred in manufacturing products sold to customers in a period. It is the aggregate of direct labor, direct materials, and overheads used in the production process. COGS apply to manufacturing firms and companies that handle physical goods.
The COGS is deducted from the sales revenue to give the gross profit. Calculating the COGS involves adding the purchases or goods manufactured to the beginning inventory. Ending inventory is deducted from the total to provide the COGS. As per the formula, the COGS does not apply to the service industry.
Answer:
Y=38.8
Y will increase by 38.8
Y=246+38.8
Y=284.8
Explanation:
Y=A. F(K, L)
Y=A. K^0.3, L^0.7
Then
Y=246
A=1
K=2000
N or L=100
Solutions
200=1(2000^0.3, 100^0.7)
Now the question says both k & N are increased by 0.20
Therefore
Y=1(2400^0.3, 120^0.7)
Y=1(10.3 + 28.5)
Y=38.8
