A sports club is organizing a weekend training camp for its members. The camp charges £45 for senior members (aged 18 and over) and £32 for junior members (aged 12-17). The club must also hire qualified coaches at £40 per coach. Regulations require one coach for every 6 junior members (or part thereof). Senior members do not require a coach but for every two junior members one senior member must attend. The sports club is aiming to raise as close to £1000 but not over.
