For his business, Gil has determined that the time it takes to finish a job varies inversely with the number of workers. This can be expressed as:
==\ensuremath{T=\frac{k}{w}}== where T = time, k is a constant, and w = number of workers. Gil’s records show that 18 workers can finish a job in 6 days. How many days will it take 12 workers to do the same job?
A 4
B 9
C 12
D 36

18 * 6 = 12 * ?
how many worker days needed?
18 * 6 worker days/job
so
12 workers * x days = 18 *6
x = 18/2
18 * 6 worker days/job
so
12 workers * x days = 18 *6
x = 18/2
