Question

Pat deposited $2000,at 6% simple intrest. how long will it be before she has $2600 in her account?

Answer 1

Simple interest=PRT  P=principal(initial amount)  R=interest rate  T=time(in years)
she wants 2600 in her account so 2600-2000=600 dollars in interest so   

600=2000*.06*T
600=120T  600/120=5  so in 5 years her account balance will be $2600
