Answer:
Statement a. is correct.
Explanation:
The effective annual rate is always higher than the nominal interest rate, as the formula is clear for any number of periods, for any interest rate:
Effective Annual Rate of return = 
Further if we calculate the present value of annuity due and ordinary annuity assuming 6 % interest rate, then:
Present value of annuity due =

= 1.06
$400.95
= $425.0089
Present value of ordinary annuity =
= $150
2.6730
= $400.95
Therefore, value of annuity due is more than value of ordinary annuity.
Statement a. is correct.
$4.40 per share
Explanation:
The computation of the earning per share is shown below:
Earning per share = (Net income - preference dividend) ÷ (Weighted average of number of shares)
where,
Net income is $640,000
Preference dividend is $72,000
And, the weighted average number of share is
= 120,000
Answer:
i) Z = 20( 80 ) + 50(20 ) = $2600
ii) $3000
Explanation:
representing products A and B as x₁ and x₂
using the given data
Max ( z ) = 20x₁ + 50x₂ ( optimal product mix for optimal profit ) ---- ( 1 )
0.8 ( x₁ + x₂ ) ≥ 0
0.8x₁ + 0.8x₂ ≥ 0 ------------ ( 2 )
also x₁ ≤ 100 --- ( 3 ) considering the amount to be sold ( sales volume )
based on the availability of raw material
2x₁ + 4x₂ ≤ 240 ----- ( 4 )
resolve equations 2, 3, and 4 graphically
x₁ = 80 units , x₂ = 20 units
back to equation 1
Z = 20( 80 ) + 50(20 )
= 1600 + 1000 = $2600
ii) To increase the number of units of A produced
given that x₁ ≤ 100 and the actual optimal units produced = 80 units
2600 + 20(100-80)
= 2600 + 20(20) = 2600 + 400 = $3000
Here is the correct answer of the given question above. The output of the North American executive purchasing roundtable in 1994 was the trend towards strategic purchasing. This result was very evident during that year. P<span>urchasing responsibilities reveals a large-scale movement of the shift during 1990 . Hope this answer helps.</span>
