Divide 54 by 3 which will get you q=18
The answer is square root of 39. 64-25=39
Amount= Deposit or initial amount ( 1+ percent increase) ^period of time
So Amount= 50(1+0.1)^3
= 50(1.1)^3
= 50(1.331)
=66.55
So she will have $66.55 in 3 years.
For this you have to get r by itself so you put 1 over 3 and move it to the other side and then you get 2/3 as an answer
