Question

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 t, after the equation is rearranged?

t equals start fraction cap a minus p over p r end fraction
t equals start fraction cap a plus p over p r end fraction
t equals start fraction cap a minus one over r end fraction
t = A − p − pr

Answer 1

I got A-P over PR which is equal to t. So the answer will be the first one, A.

Answer 2

Option (A) is the correct answer

Explanation:

The given equation is A = p + prt which is now to find the accumulated amount A, of an investment with principal P, and interest rate r, over the time t

We have to find value of t by rearranging equation.

A = P + prt

A - P = prt

(A - P) / pr = t

Option (A) t equals start fraction cap a minus p over p r end fraction.
