First off we need figure out approximately how much she made in between weeks 2 and 24.
430 - 47 = 383. So now we know she made 383 dollars in 22 weeks. Then just divide your answer with the number of weeks.
383÷22=17.409 | which rounds up to B.) 17.41
-2b + 7 > 27.5
- 2b > 27.5 - 7
- 2b > 20.5
b < - 10.25
