Answer: Option C,
The correct answer is:
B)15h+135≥575
We can calcutate with this inequality (15h+135≥575) the minimun number necesary of hour that Samantha have to work for buy the plane ticket.
15h+135≥575
15h≥575-135
15h≥440
h≥440/15
h≥29.333 then h≥30
Samantha need work greater tan or equal to 30 hours.
To chek:
h=29 ⇒15(29)+135=570<575
h=30 ⇒15(30)+135=585>575; therefore h≥30
