In your journal, you identified careers that involve irrational numbers. You brainstormed or researched jobs that use pi or Euler’s number to do their work.

Question

Imagine that your friend loves to plan parties, and he wants to be an event planner someday. He does not think he needs to know how to find a number between two rational numbers. He also says he will never use pi again in his life after math class. You think of some of the tasks he might need to do as an event planner:

Decide how many cakes to order when a party could have as few as 50 people and as many as 100 people.
Choose a round table that is the correct size to fit six people.
Make a prediction about how much to budget for the decorations at a party when the customer is still deciding between $10 floral arrangements and $30 floral arrangements.
In your post, explain to your friend how he will use the skill of finding a number between two rational numbers in his dream career:

Choose one of the examples from the list above, and represent the example with a mathematical statement.
Summarize to your friend why he will need both rational and irrational numbers as an event planner.

Answer 1

As an event planner, your friend will need to use the skill of finding a number between two rational numbers. This skill is necessary when deciding how many cakes to order for a party that could have as few as 50 people and as many as 100 people. By finding a number between the two rational numbers, your friend can ensure that there are enough cakes for all the guests without overordering.

For example, if there are 50-100 people expected at a party, your friend would need to find a number between 50 and 100, such as 75. This way, he can order an appropriate number of cakes to accommodate the most likely number of guests.

In addition to this, your friend will also need to use rational numbers when choosing a round table that can fit six people. Rational numbers, which include whole numbers and fractions, will help him determine the correct size of the table that is suitable for the gathering.

While your friend may not think he will use pi or other irrational numbers after math class, he will still need rational numbers and occasional estimates in his career as an event planner. Rational numbers will help him make accurate calculations and decisions, such as determining budgets for decorations. These numbers are essential for planning and organizing successful events.
