There are 3 workers producing chairs in a furniture factory. Each of them produces 4 chairs an hour. As a group, they produce an additional chair every 6 hours. In total, how many chairs have been produced after 6 hours? Let's answer step by step:
The workers produce a combined total of 3 workers * 4 hours = 12 chairs every hour. After 6 hours, they have therefore produced 12 * 6 = 72 chairs. Adding the additional chair means the total amount of chairs produced is 72 + 1 = 73 chairs. The answer: 73.
