Solution: The cost of repairing the current machine = $800. The cost of new machine = $3,600

Since the new machine lasts for three years, the average cost per year = $\(\frac{3,600}{3}\) = $1,200.

Thus, the required percentage = \(\frac{\left(1,200-800\right)}{800}\) × 100(%) = 50%.

Therefore, D is the correct answer.

Answer D

Total cost for repairs $$=\ 800\ dollars$$
Total cost for new purchase= $$=\ 3600\ dollars$$
Average cost of new machine
$$=\frac{\cos t\ of\ new\ machines}{\cos t\ of\ the\ years\ it\ will\ last}=\frac{3600}{3}=1200$$ $$\%\ difference=\frac{1200-800}{800}\cdot100=50\%$$
$$Answer\ is\ Option\ D$$
