Answer: a) $620; b) 7.75 %

Step-by-step explanation: To calculate the eran money y due to the investment we have to add the two quantities.

the 4% for $2000 and 9% for $6000

This is: $80+$540 = $620

Finally to determine the percent interest for his total investment, we have to divide the erned money over the total money, that is:

% earned=$620/$8000 = 0.0775 the 7.75 %
