The equation A = p + prt is used to find the accumulated amount, A, of an investment with principal, P, a certain interest rate,
r, and over time, t. What is the value for r, after the equation is rearranged? r equals start fraction cap a plus p over p t end fraction
r equals start fraction cap a minus p over p t end fraction
r equals start fraction cap a minus one over t end fraction
r = A − p − pt
yes i agree because if all the integers are positive, the answer stays positive which means if you know your integer rules: a positive divide by a positive it stays positive. its the same thing for all the other operations. hope this helps.
