The simple intrest I on an investment of P dollars at an intrest rate r for t years is given by I=prt. Find the time it would take to earn 1400 in intrerst on an investment of 27,000 at a rate of 4.2persent

Therefore time = 1.23 years.

Step-by-step explanation:

Formula of simple interest:

= interest in dollar

P= Principal in dollar

r= rate of interest

t= time in years

Given that,

= $1,400 , P=$27,000 , r=4.2%= 0.042 and t = ?

Putting the value of P, and r

      years

Therefore time = 1.23 years.
