this problem has the same structure as the one I answered for you 4 minutes ago.

The only difference is that one has to conclude that the amount of interest is $166

let me know what rate you got.

Just like before

R = I/PT

= 166/(2000x2)

= 166/4000

= .0415

= 4.15%

She deposited 2000 and got back 2166

how much did she make ?

Isn't that the interest ?
