Question 1015075
Use the compound balance formula {{{A = P(1+r/n)^(nt)}}}.
 For the first year, P = 100, r = 0.02, n = 1, and t = 1.
==>{{{ A = 100(1+0.02/1)^1 = 102}}}
Hence the balance after 1 year is $102.

For the next 4 years, 
P = 102, r = 0.015, n = 1, and t = 4.

Hence, {{{A = 102(1+0.015/1)^4 = 102*1.015^4 = 108.26}}}

Therefore the account will be worth $108.26 at the end of the 5-year period.
