Applecross Dental Services is investigating expanding its operations by acquiring additional teeth cleaning equipment. The equipment would cost $146,000 and management has estimated that it would result in net cash inflows of $14,400 per year. The equipment would have a 15-year useful life with an expected salvage value of $14,200. (Ignore income taxes.) Required: 1. 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 $14,400, 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 retun 2-b. This part of the question is not part of your Connect assignment.

please note there are several required answers

How do I solve for the chart?

Foster Company wants to buy a special automated machine to replace an existing manual system.  The initial outlay (cost) is $3,500,000.  The new machine will last 5 years with no expected salvage value.  The expected annual cash flows are as follows:                 Year Cash Inflow Cash Outflow           0  $                            -    $          3,500,000.00           1  $        3,900,000.00  $          3,000,000.00           2  $        3,900,000.00  $          3,000,000.00           3  $        3,900,000.00  $          3,000,000.00           4  $        3,900,000.00  $          3,000,000.00           5  $        3,900,000.00  $          3,000,000.00                           Foster has a cost of capital equal to 10%.                           1.   Calculate the payback period.       Payback period:   years
