Answer:
Variable overhead efficiency variance= $544 favorable
Explanation:
Giving the following information:
Variable overhead 0.90 hours $ 3.40 per hour
Actual output 4,400 units
Actual direct labor-hours 3,800 hours
<u>To calculate the variable overhead efficiency variance, we need to use the following formula:</u>
<u></u>
Variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
Variable overhead efficiency variance= (3,960 - 3,800)*3.4
Variable overhead efficiency variance= $544 favorable
Standard quantity= 4,400*0.9= 3,960
Answer:
Value of x maximising profit : x = 5
Explanation:
Cost : C(x) = x^3 - 6x^2 + 13x + 15 ; Revenue: R(x) = 28x
Profit : Revenue - Cost = R(x) - C(x)
28x - [x^3 - 6x^2 + 13x + 15] = 28x - x^3 + 6x^2 - 13x - 15
= - x^3 + 6x^2 + 15x - 15
To find value of 'x' that maximises total profit , we differentiate total profit function with respect to x & find that x value.
dTP/dx = - 3x^2 + 12x + 15 = 0 ► 3x^2 - 12x - 15 = 0
3x^2 + 3x - 15x - 15 = 0 ► 3x (x +1) - 15 (x + 1) = 0 ► (x+1) (3x-15) = 0
x + 1 = 0 ∴ x = -1 [Rejected, production quantity cant be negative] ;
3x - 15 = 0 ∴ 3x = 15 ∴ x = 15/3 = 5
Double derivate : d^2TP/dx^2 = - 6x + 12
d^2TP/dx^2 i.e - 6x + 12 at x = 5 is -6(5) + 12 = - 30+ 12 = -8 which is negative. So profit function is maximum at x = 5
Frank and lillian gilbreth developed the principle of motion economy, which said that every job could be broken down into a series of elementary motions. The motion economy has principles that are in place to improve the manual work within a manufacturng career field. These are to help a manufacturer worker not be exhausted so quickly and reduce the trauma that may occur within this career field.
It could invade the privacy of the shopper when trying things on. All of the actions the customer does is being recorded, not to mention the customer has no idea who exactly is monitoring the cameras, and how many people have access to it. It could become a serious problem.
Answer:
A. Decrease
Explanation:
In investment appraisal with the method of Net Present Value, the bone of contention and the central matter is the TIME VALUE OF MONEY.
In the above scenario, the initial working capital was 100% released in proportions of 40%, 40% and 20%, throughout the 3 years of the project. However, if the reverse had been the case, i.e. parting with more cash now and the requirement of working capital now becomes: Year 0 = -10,000, Year 1 = - 10,000, Year 2 = -10,000, Year 3 = +30,000; the NPV would definitely shrink because the value of 10,000 each in Years 0-2 would not be the same when it is recovered from the project in year 3. The value will be smaller and hence the NPV of the project would have decreased as a result of the time value of money.
