Need help solving this please: You enter into a 5 year net lease with tenant for 2,000 sq. ft. of space. The lease states that you will provide a TI allowance of $20 per sq. ft. Assume that the TI allowance is used to fund improvements in the tenants space at the beginning of the first year. In return for using the space, the tenant will pay an initial annual rent of $40 per sq. ft. at the end of the first year of the lease term, with subsequent increases to $41 per sq. ft. in year 2, $42 ...

It's too bad the HP-Prime is not just like any other USB device. For example Android phones. I'm a long time Linux user and find Windows impossible to use. It's really not worth my time to try to set up a virtual box machine with Windows. I really have no need for Windows at all, and detest working with it because there are so many problems. (read...)

I thought that I remember that you get 2040 when you do this, however, using an emulator, this doesn't work. I am in discussion about this with James Thomson who wrote PCalc for iOs, which I use as my HP41 replacement (for simple calculations). Your answer would really help me. Cheers, Nikolaus (read...)

The P/Yr on your calculator was set to 1. To get the answer, you need to change it back to 12. Or you can simply a push a pin into the reset hole on the back of the 10bII+, this will put the calculator back to factory default settings. (read...)
