To assess the cost-effectiveness of investing in an availability increase from 99.9% to 99.99% for a single year, it's essential to calculate the additional revenue generated by the improved availability. Using the formula 1000000÷100×0.09, which represents 0.09% of the current revenue of $1,000,000, the calculated value is $900. This indicates that the potential increase in revenue due to the higher availability is $900. Given that the investment cost is $2,000, the gain falls short of covering the investment, making the decision not to pursue the availability increase financially impractical. Therefore, option A is the correct choice, aligning with a thorough cost-benefit analysis and demonstrating that the increase in availability is not worth the $2,000 investment for a single year of usage.
