In a PCB factory, a plating line was bought 6 years ago for ($300,000+10*D8). Since it caught fire last night, its life span is much shortened and remains for only 1 more year from now. There would be no salvage value. (Round off your final answers to 2 decimal places)

Since the fire suddenly shortened the life span of the plating line, the engineer wants to migrate the risk by subscribing a special Refitting Service Plan so that the life span of the new plating line can be extended to 10 years. The first annual refitting service charge ($15,000) will be paid at the Day 1 of purchasing the new equipment. As the equipment ages, this charge is expected to be increasing at ($1,500+D8) every year. The MARR is 10% per annum.

[NOTE: Year 0 is today; Year 1 is Day 1 of purchasing the new equipment]

(c) List all the values of the given factors required for the calculation of gradient annuity at Year 1.

(d) Draw a cashflow diagram to illustrate your payment schedule.

(e) How much would be the total Refitting Service charges discounted back to the Day 1 of purchasing the new equipment?
