The formula used to calculate simple interest is modeled by I=prt, where I=simple interest, p=principle, r=interest rate, and t=time, measured in years. Which of the following options represent(s) an alternative equivalent version of the simple interest formula? Select all that apply.

T = l/rp
L - rt = p
P = l / rt
L = p + rt
L = trp

L - rt = p and P = l / rt are alternative equivalent versions of the simple interest formula.
