I just need help with the last part (the values in red). Thank you!!

Exercise 21A-21 a-d Pronghorn Incorporated leases a piece of equipment to Larkspur Corporation on January 1, 2017. The lease agreement called for annual rental payments of $5,613 at the beginning of each year of the 4-year lease. The equipment has an economic useful life of 6 years, a fair value of $26,600, a book value of $21,600, and both parties expect a residual value of $8,200 at the end of the lease term, though this amount is not guaranteed. Pronghorn set the lease payments with the intent of earning a 7% return, and Larkspur is aware of this rate. There is no bargain purchase option, ownership of the lease does not transfer at the end of the lease term, and the asset is not of a specialized nature Click here to view the factor table (For calculation purposes, use 5 decimal places as displayed in the factor table provided.)
