HHenry is going on a trip to Brazil. He is currently deciding which cities he will visit during his stay. The table below shows
Karo-lina-s [1.5K]
First, sum up the total expenses for the original plan

Duque de Caxias + Campinas + Rio de Janeiro + Guarulhos = 242+185+193+120 = R$740

It is clearly over the intended budget. The average cost per itinerary is around R$200 so we will consider making a swap on either Duque de Caxias and Rio de Janeiro.  Possible answers are (b) or (c)

for (b) Replace Duque de Caxias with Fortaleza, we will have

Fortaleza + Campinas + Rio de Janeiro + Guarulhos =
⇒ 201+185+193+120 = R$699  ⇒ This is exactly the budget intended for the trip

for (C) Replace Rio de Janeiro with Porto Alegre
Duque de Caxias + Campinas + Porto Alegre  + Guarulhos =
⇒ 242 + 185 + 153 +120 = R$ 700 ⇒ This is over R$1

The answer is (b)
