Answer 1

I don't know what ti 85 calculator is, but as soon as I can see all you need to do for the first question is to replace t by 15 at formula and calculate result. You can use pen and paperti do this.

As concern for the second question, you need to replace A(t) by dollars acured value and solve problem for t, by applying logarithm to both part of equation.
