please do hand calculations. thanks

This is all i am given

5. (20 pts) In 2017, Tesla unveiled a plug-in electric tractor-trailer. It is expected to cost $200,000 when it enters production next year and have an operating cost of about $1.26/mile. A regular diesel tractor-trailer costs around $120,000 and has an operating cost of about $1.51/mile at present diesel prices. Based on a 10-year useful life and assuming no salvage value (to simplify the calculations), how many miles per year must a trucker drive for the Tesla to be preferred over a conventional diesel truck? Assume your MARR is 12% per year
