The Answer of Using the formula $A = P \left( 1 + \frac { r } { n } \right) ^ { n t }$ , find the interest on an investment of $1200, at an interest rate of 12% for 5 years, if the interest is compounded quarterly.

Using the Formula A=P(1+rn)ntA = P \left( 1 + \frac { r } { n } \right) ^ { n t }A=P(1+nr​)nt

Using the Formula $A = P \left( 1 + \frac { r } { n } \right) ^ { n t }$
