$($IRR calculation$)$ Determine the IRR on the following projects:

a$.$ An initial outlay of $$11,000$ resulting in a single free cash flow of $$17,224$ after $8$ years

b$.$ An initial outlay of $$11,000$ resulting in a single free cash flow of $$46,613$ after $11$ years

c$.$ An initial outlay of $$11,000$ resulting in a single free cash flow of $$113,806$ after $23$ years

d$.$ An initial outlay of $$11,000$ resulting in a single free cash flow of $$13,883$ after $4$ years

a$.$ What is the IRR of a project with an initial outlay of $$11,000$ resulting in a single free cash flow of $$17,224$ after $8$ years?
