A conveyor system costs $$100,000$ to install. The Salvage value of the convey or System decreases by $$20,000$ kach year until its salvage value is at $$0,$ at which point it no longer decrates.

The cost to operate and maintain the convey or system the first year is $$20,000$; this cost increases by $5\%$ per year. What is the uptimal replacement interval and minimum EUAC for the conveyor systam, assuming a MARR of $12\%$ is USed? Note that the oppimal replacement interva$)$ is more than $($and not equal to$)n=13$ and less than and $($not equal to$)n=16$ so you do not nerel to seouch for an $n$ outside this range $-$ In fact you will need to only check two values for $n$ based on this range
