Final answer:
The provided equation N = 725/t appears to have a typo, as solving it with N as 100 employees suggests it would take 7.25 days, which doesn't match the provided options. If the intended equation should be N = 725*t, it would not result in a whole number of days matching the answer choices.
Step-by-step explanation:
The student's question involves solving an algebraic equation to find out how many days (t) it will take for 100 employees to be able to perform a certain task. The equation provided is N=725/t. To find t when N equals 100 employees, we can rearrange the equation to t = 725/N. Substituting 100 for N gives us t = 725/100, resulting in 7.25 days. However, since the options provided are in whole days, it is likely that the question intends for days to be considered in whole numbers and there is a mistake in the equation provided. If we ignore the error and assume the equation should be N = 725*t, solving for t results in t = 100/725, which does not match any of the options given either. Therefore, there seems to be a misunderstanding or typo in the equation provided in the question.
