Answer:
   a) $336
   b) $1036
Step-by-step explanation:
a) The interest is computed using the formula ...
   I = Prt
where P is the amount invested at rate r for t years.
   I = $700·0.08·6 = $336
The interest earned is $336.

b) The balance of the account is the sum of the original amount and the interest earned:
   balance = $700 +336 = $1036
The balance of the account is $1036.
