formula a = p (1+rt) A is the principal plus simple interest , P is the principal , r is the interest rate , and t is the time solve equation for r

Question

someone please help like right about NOW 

Answer 1

I think A is the same as a in your question, so I solve it like this  

 

 

  a = p (1+rt)

 

  a = p + prt

 

prt = a - p 

 

  r  = (a - p) / pt

Answer 2

                 a = p(1+rt)

 

              a/p = 1 + rt

 

         a/p - 1 = rt

 

(a/p)/t - (1/t) = r
