Kelly opened a bank account that earns 1.2% simple interest each year. after 7 years, kelly will earn $126 in interest. how much did kelly deposit when she opened the account?

13.4 dollars

Step-by-step explanation:

The final amount is given by:

F=I(1+rt)

Where

I= initial amount

r= interest rate

t= time interval

F= final amount

Now in our case

r= 1.2

t= 7

F= $126

Therefore I=F/(1+rt) = 126/(1+1.2*7) = 13.4 dollars.
