Hi there
To find The interest earned
The formula of the simple interest is
I=prt
I interest earned?
P principle 3000
R interest rate 0.07
T time 2 years
So
I=3,000×0.07×2
I=420

Good luck!

Answer 2

Is the question asking for interest? If so, just use the equation interest=t=principal*rate*time (I=PRT)
In this case, we just mulitiply 3000 by 2 and 0.07 to get 420. Now, just add this to the principal amount to get $3420 as the ending amount.
