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.
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
