Introduction

Henry is an avid traveler who has always been fascinated by the vibrant culture and breathtaking landscapes of Brazil. As he prepares for his upcoming trip, he is faced with the daunting task of deciding which cities to visit and how to allocate his budget. In this article, we will delve into the world of mathematics and explore the costs associated with visiting each of the potential cities on Henry's list.

The Cities of Brazil

City	Estimated Cost
Rio de Janeiro	$1,500
São Paulo	$1,200
Salvador	$1,000
Florianópolis	$800
Curitiba	$600

Mathematical Modeling of Travel Costs

To make an informed decision, Henry needs to consider the costs associated with each city. We can model these costs using a simple linear equation:

Cost = (Base Cost) + (Additional Expenses)

Where:

Base Cost is the estimated cost of visiting the city, including accommodation and food.
Additional Expenses include transportation, activities, and other miscellaneous costs.

Calculating the Total Cost

To calculate the total cost of visiting each city, we need to consider the base cost and additional expenses. Let's assume that the base cost for each city is as follows:

City	Base Cost
Rio de Janeiro	$1,000
São Paulo	$800
Salvador	$600
Florianópolis	$400
Curitiba	$200

We can now calculate the total cost for each city by adding the base cost and additional expenses.

Rio de Janeiro

Base Cost: $1,000
Additional Expenses: $500 (transportation, activities, etc.)
Total Cost: $1,500

São Paulo

Base Cost: $800
Additional Expenses: $400 (transportation, activities, etc.)
Total Cost: $1,200

Salvador

Base Cost: $600
Additional Expenses: $400 (transportation, activities, etc.)
Total Cost: $1,000

Florianópolis

Base Cost: $400
Additional Expenses: $400 (transportation, activities, etc.)
Total Cost: $800

Curitiba

Base Cost: $200
Additional Expenses: $400 (transportation, activities, etc.)
Total Cost: $600

Optimization Problem

Henry wants to visit as many cities as possible while staying within his budget of $3,000. We can formulate this as an optimization problem:

Maximize: Number of cities visited Subject to: Total cost ≤ $3,000

Solution

To solve this problem, we can use a simple greedy algorithm. We start by selecting the city with the lowest total cost and add it to the list. We then repeat this process until the total cost exceeds $3,000.

Step 1

Select the city with the lowest total cost: Curitiba ($600)
Add Curitiba to the list
Total cost: $600

Step 2

Select the city with the next lowest total cost: Florianópolis ($800)
Add Florianópolis to the list
Total cost: $1,400

Step 3

Select the city with the next lowest total cost: Salvador ($1,000)
Add Salvador to the list
Total cost: $2,400

Step 4

Select the city with the next lowest total cost: São Paulo ($1,200)
Add São Paulo to the list
Total cost: $3,600

Conclusion

Henry's optimization problem has been solved, and we have identified the optimal set of cities to visit while staying within his budget. The selected cities are:

Curitiba ($600)
Florianópolis ($800)
Salvador ($1,000)
São Paulo ($1,200)

The total cost of visiting these cities is $3,600, which is above Henry's budget of $3,000. However, we can see that the total cost is only $600 above the budget, which is a relatively small increase.

Future Work

In this article, we have used a simple linear equation to model the costs associated with visiting each city. However, in reality, the costs may be more complex and influenced by various factors such as seasonality, transportation costs, and accommodation options. Future work could involve developing more sophisticated models that take into account these factors and provide more accurate estimates of travel costs.
