Final answer:
To find n(t), you need to calculate the rate of job growth over the 10 weeks and multiply it by the number of weeks (t).
Step-by-step explanation:
To find n(t), we need to calculate the rate of job growth over the 10 weeks. The job growth rate can be found by dividing the increase in the number of jobs (11.7 million - 11.3 million = 0.4 million) by the number of weeks (10). So, the job growth rate per week is 0.4 million divided by 10, which equals 0.04 million.
To find n(t), we can then multiply the job growth rate per week (0.04 million) by the number of weeks (t). Therefore, n(t) = 0.04 million * t.
For example, if t is 5 weeks, then n(t) = 0.04 million * 5 = 0.2 million.
