Need solving this problem:
jamal is planning to invest up to 24,000 in city bank or state bank. he wants to invest at least 3,000 in city bank, but not more than 11,000; since state bank does not insure more than $18,000, he wants to invest no more than this amount in state bank. the interest at city bank is 6%, and the interest at state bank is 11 %. how much should he invest in each bank to earn the most interest?

$24,000 > City or State Bank
$3,000 < City Bank < $11000
State Bank< $18,000
City Bank = .06 of interest
State Bank = .11 of interest

State Bank - (18, 000)(.11)> $1980
                                                          } Total Interest = $2,430
City Bank - (6000)(.06)>$ 360

State Bank - (13000)(.11) > $1,430
                                                             } Total Interest = $2,090
City Bank - (11000)(.06) > $660

State Bank- (17000)(.11) >$ 1870
                                                               } Total Interest = $2,290
