Since the atom has 31 protons, that means it's an isotope of gallium. Looking up gallium, you can determine that in nature it's composed of the two stable isotopes, gallium-69 and gallium-71, which have 38 and 40 neutrons respectively. Looking further, you will find that gallium-62 has a half life of 116.18 milliseconds which means it's quite unstable.</span>

Answer:
the payback period is 14 months
Explanation:
The computation of the payback period is shown below:
Profit is
= $2,000,000 - $1,669,426
= $330,574
Now payback period is
= 1 + $330,574 ÷ $1,669,426
= 1 +0.198 years
= 1.198 years
= 14.37 months
= 14 months
Hence, the payback period is 14 months
Answer:
The alternative that should be chosen assuming identical replacement is:
Alternative B.
Explanation:
a) Data and Calculations:
Alternatives:
A B
First Cost $5,000 $9,200
Uniform Annual Benefit $1,750 $1,850
Useful life, in years 4 8
Rate of return 7% 7%
Annuity factor 3.387 5.971
Present value of annuity $5,927.25 $11,046.35
Net cash flow $927.25 $1,846.35
b) Alternative B yields a higher return than Alternative A. Since the two alternatives are based on the same rate of return, Alternative B will bring in a higher annual benefit, even when discounted to the present value.
