Applecross Dental Services is investigating expanding its operations by acquiring additional teeth cleaning equipment. The equipment would cost $$150,000$ and management has estimated that it would result in net cash inflows of $$14,900$ per year. The equipment would have a $15-$year useful life with an expected salvage value of $$13,500.($Ignore income taxes.$)$

Required:

Compute the equipment's IRR. $($Hint: Use Microsoft Excel to calculate the discount factor$($s$).)($Do not round intermediate calculations and round your final answer to $1$ decimal place.$)$

Internal rate of return

$2-$a$.$ Assume that instead of $$14,900,$ the salvage value in $15$ years for the new equipment will be $$0.$ Compute the IRR under this new assumption. $($Do not round intermediate calculations and round your final answer to $1$ decimal place.$)$

Internal rate of return
