Answer:
C. 4 weeks
Step-by-step explanation:
We have the formula

We are looking for the value of t (number of weeks) when s = 150.
So, we isolate t (well, almost isolate, because it would be hard to read)

If we replace s by 150 we get:

We have 7t = 30.25. If we divide both sides by 7 we get the number of weeks: 4.32... so rounding it down to 4.
