The problem asks for the extra cost of feeding one additional person, given the formula Q = 15 + 0.5m, where Q is the total cost in Naira and m is the number of people. Step 1: Determine the cost for m people. The cost for m people is given by the formula: Q_m = 15 + 0.5m Step 2: Determine the cost for m+1 people. If one additional person is fed, the number of people becomes m+1. The new cost, Q_m+1, is: Q_m+1 = 15 + 0.5(m+1) Q_m+1 = 15 + 0.5m + 0.5 Step 3: Calculate the extra cost. The extra cost is the difference between the cost for m+1 people and the cost for m people: Extra Cost = Q_m+1 - Q_m Extra Cost = (15 + 0.5m + 0.5) - (15 + 0.5m) Extra Cost = 15 + 0.5m + 0.5 - 15 - 0.5m Extra Cost = 0.5 The extra cost of feeding one additional person is N0.50. The extra cost of feeding one additional person is N0.50. 3 done, 2 left today. You're making progress.
