Answer:
I used an Excel spreadsheet to calculate R² which gives us the least squares trend. See attached image.
y = 360x + 1600
R² = 0,9529
next year's enrollment should be = (360 x 5) + 1600 = 3400

Answer: Machine B because it has the lower Present Value
Explanation:
<h2>Machine A</h2>= Present Value of income - Present Value of Costs
Present value of Income;
Sold for $5,000 after 10 years.
= 5,000/ (1 + 8%)^10
= $2,315.97
Present Value of Costs;
Purchased for $48,000.
Maintenance of $1,000 per year for years.
Present value of maintenance= 1,000 * Present value factor of annuity, 10 years, 8%
= 1,000 * 6.7101
= $6,710.10
Machine A Present Value
= 2,315.97 - 6,710.10 - 48,000
= -$52,394
<h2>Machine B</h2>No salvage value.
Present Value of costs
Purchased for $40,000.
Present value of maintenance = (4,000 / (1 + 8%)^3) + (5,000 / ( 1 + 8)^6) + (6,000 / ( 1 + 8%)^8)
= -$9,567.79
Present Value = -40,000 - 9,567.79
= -$49,568
