Answer:
12%
Step-by-step explanation:
Annual net income:
= Increase in annual revenue - Increase in annual costs
= $220,000 - $160,000
= $60,000
Average investment:
= (Initial investment + Salvage value at the end) ÷ 2
= (980,000 + 20,000) ÷ 2
= $500,000
Annual rate of return:
= (Annual net income ÷ Average investment) × 100
= ($60,000 ÷ $500,000) × 100
= 12%
