Answer:
Given that Program instructions consists of:
- 60% floating point multiply
- 20% floating point divide
- 20% other instructions
Amdahl's law states that:
Execution time affected by improvement = (Execution time after improvement/ Amount of improvement) + (Execution time unaffected)
Assuming initially that floating point multiply, divide and other instructions have same clocks per instruction (CPI).
Part (a)
New execution time after improvement with multiply = (60) / 8 + (20 + 20) = 47.5
New execution time after improvement with Divide = (20) / 3 + (60 + 20) = 86.67
New system should be 4x faster which means new execution time should be below = 100/ 4 = 25.
Therefore, Management's goal can NOT be achieved by making the improvement with multiply or divide alone.
Part (b)
New execution time after improvement with multiply and divide = (60 / 8) + (20 / 3) + 20 = 34.17
Speed up = execution time of original machine / Execution time of new machine = (100 / 34.17) = 2.93
Therefore, new machine is 2.93 times faster than original machine.
Answer:
Cost of leasing over buying is $144.59
Explanation:
For computing the cost of leasing the laptop over buying it outright, we have to calculate the present value is shown below:
Given that,
Future value = $0
Rate of interest = 14% ÷ 12 months = 1.17%
NPER = 4 years × 12 month = 48 months
PMT = $75
The formula is shown below:
= PV(Rate;NPER;-PMT;FV;type)
So, after solving this, the present value is $2,744.59
And, the buying amount is $2,600
So, the difference is
= $2,744.59 - $2,600
= $144.59
Answer:
a.Georgeland has an absolute but not a comparative advantage in producing clothing.
Explanation:
A country has a comparative advantage in production if it produces at a lower opportunity cost when compared with other countries.
A person has an absolute advantage in production if it produces more quantities of the good when compared with other countries.
Georgeland produces more quantities of both food and clothes when compared to Alland, so it has absolute advantage in both activities .
The opportunity cost of georgeland in producing clothes = 36 / 18=2
The opportunity cost of georgeland producing food = 18 / 36 = 0.5
For Alland,
the opportunity cost of producing clothes = 32 / 16= 2
the opportunity cost of producing food = 16 / 32 = 0.5
Neither countries don't have a comparative advantage in the production of either clothes of food bedside they have the same opportunity costs in both activities.

Answer:
Raise the marketing spend to raise visibility.
Explanation:
