There are a bunch of ti-emulators here but no ba 2+ that i can see. does this calculator have specific functions for finance?

yes it can calculate interest,pv,fv,i,r,and all that shit

all these things can be calculated with every calculator if you just take a moment to think about how the theory works. You will definitely benefit from not using built in functions

the prof doesnt know the formulas and is not willing to teach us, he said to buy the calculator.
ive been using formulas but stuff just got fuckin harrd.
here try solving if anyone knows how
A local finance company quotes a 16 percent interest rate on one-year loans. So, if you borrow $30,000, the interest for the year will be $4,800. As you must repay a total of $34,800 in one year, the finance company requires you to pay $34,800/12, or $2,900, per month over the next 12 months.
whats the effective monthly rate?
the answer is 2.36 but how do i get it?

here is the formula, but how do i get r?
PVA = $30,000 = $2,900 ×
(1 - [1/(1+r)12])/r
