 Old Machine New Machine Life at purchase: 3 years 3 years Remaining life: 1 year 3 years Cost at purchase: \$9,000 \$12,000 Depreciation (p.a.): \$3,000 \$4,000 Revenue (p.a.) \$6,000 \$7,000 Expenses- year 1 year 2 year 3 \$2,000 \$1,000 \$1,500 \$2,250 Salvage Value Book Value Book Value

She believes that the second-hand market value of either machine will decline over time in line with the depreciation schedule (for example, the old machine should sell for \$3,000 today). If there are no taxes, and Gillian’s required rate of return is 15% p.a.:

i) What is the optimal replacement cycle for the new machine?

ii) Should the old machine be replaced now, or next year?

(Note: If you are unable to complete part (i), state any necessary assumptions and then complete part (ii).)

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
