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?
The workers produce a combined total of 3 workers * 4 hours = <T>multiply(3, 4)=12 chairs every hour.
After 6 hours, they have therefore produced 12 * 6 = <T>multiply(12, 6)=72 chairs.
Adding the additional chair means the total amount of chairs produced is 72 + 1 = <T>add(72, 1)=73 chairs.
