Salina currently has an account balance of $1,047.69. Her initial deposit on the account was $630 and it earned 3.9% simple interest. How long has Salina held the account? I did A=prt and got about 42 years but the answer was wrong. The choices are 26,17,10 and 43(which is what I answered and got it wrong). Please help!
