formula: A(t) = A•1.05^{t} where original amount A grows at 1.05 rate compounded annually for t years.

i) 750 = 500•1.05^{t} solve for t...1.5 = 1.05^{t} ... ln 1.5 = t ln1.05 ... you can finish this task.

ii) Compute A(8) and then subtract original A=500 to get accumulated interest ("savings"<---should be "earnings")
