Waec Model Questions Vol1 2018 Christian Religious Studies Question 12

A church community plans a dinner service with three volunteer roles: cooks, servers, and cleaners. Each cook can prepare \(12\) meals per hour, each server can serve \(20\) meals per hour, and each cleaner can clean \(30\) seats per hour. The service requires at least \(240\) meals prepared, all meals served, and \(180\) seats cleaned. The team has \(4\) cooks who can work up to \(4\) hours each, \(3\) servers who can work up to \(3\) hours each, and \(2\) cleaners who can work up to \(2\) hours each. Any additional volunteer may work up to \(5\) hours and can be assigned to any one of the three roles, with the same productivity rates as above. Determine the minimum number of additional volunteers needed, and specify one possible composition of roles for these volunteers, to meet all three requirements.
