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.
Generally, it is important to be upfront, express regret that the company can't meet the deadline, and tell the customer how the problem will be fixed.
Answer:
a) a monetary unit for measuring and comparing the relative values of goods.
Explanation:
In the case when the economist said that money could be treated as the store of value so this means that it represent one of the functions of money which can be stored and retrieve later onwards
Also it is a monetary unit that could be used for measuring and also compared the goods value
Therefore the option a is correct
The estimated cost of the assurance-warranty is $350. The accounting for warranty will include a credit to Unearned Warranty Revenue, $900
Explanation:
- Entertainment Tonight, Inc. manufactures and sells stereo systems that include an assurance-type warranty for the first 90 days. Entertainment Tonight also offers an optional extended coverage plan under which it will repair or replace any defective part for 2 years beyond the expiration of the assurance-type warranty. The total transaction price for the sale of the stereo system and the extended warranty is $3,000. The standalone price of each is $2,300 and $900, respectively. The estimated cost of the assurance-warranty is $350. The accounting for warranty will include a credit to Unearned Warranty Revenue, $900.
- Unearned extended warranty revenue is given to be as an unearned revenues in accrued liabilities in the balance sheets.
- Revenue which comes from separately priced, self-insured service contracts is reffered at the point of sale.
- Unearned revenue is a money which is received from a customer for work that has not been performed still.
Answer:
Answer is explained in the explanation section below.
Explanation:
Data Given:
Material Cost Per Trailer = $500
Material Cost plus Profit Per Trailer (15%) = $500 + 75 = $575
Selling Price = $1000
Labor Cost Remaining Per Trailer = $425
Formula to Calculate the number of Trailers:
X = X1 (
)
Where,
N = number of Trailers
S = Slope Parameter
X = $425
X1 = $700
So, First we need to find the slope parameter, in order to calculate the number of trailers to be built.
S = 
where, α = 0.85 rate of improvement.
Plugging in the values into the formula, we get:
S =
S = -0.234
Now, we can easily find the number of trailers.
X = X1 (
)
Plugging in the values,
425 = 700 x (
)
Solving For N, we get:
N = 8.4 Trailers
N = 9 Trailers.
Hence, 9 Trailers must be built in order to realize this rate of profit.
