Answer:
The economic savings for purchasing the Janome 15 model = $3000
Explanation:
<u><em>Step 1: Calculate Total cost of purchasing Janome 12 model</em></u>
Retail cost = 10000
Lifetime maintenance = 500
Operating expenses = 1500 × 5 = 7500
Total cost = 18000
<u><em>Step 2: Calculate total cost and benefit of Janome 15</em></u>
Retail cost = 12000
Lifetime maintenance = 500
Operating expenses = 1500 × 5 = 7500
total cost = 20,000
Calculate benefits of Janome 15
increase in productivity = 500 × 5 = 2500
reduction in operating expenses = 500 × 5 = 2500
total benefit = 5000
<u><em>Step 3: Calculate net cost of Janome 15 </em></u>
net cost = total cost - total benefit
= 20,000 - 5000
= 15000
<u><em>Step 4: Calculate net benefit of buying Janome 15 </em></u>
18000 - 15000 = 3000
