Excel Formulas and Problem Solving

What three key elements are mentioned as skills needed to turn a real-life problem into an Excel formula?

• Planning, Basic Math, and Knowledge

• Creativity, Logic, and Speed

• Programming, Data Entry, and Analysis

• Research, Collaboration, and Presentation

An event has 614 RSVP'd guests, but the venue only seats 550. How many extra chairs are needed?

• 50

• 64

• 74

• 100

The problem of determining extra chairs needed for an event is an example of what type of basic math problem?

• Addition

• Multiplication

• Division

• Subtraction

To make a simple subtraction problem solvable in Excel, what character must precede the numbers or cell references?

• +

• -

• *

• =

What is a key advantage of using cell references (e.g., A2-B2) instead of direct numbers in an Excel formula?

• It makes the formula shorter

• It allows the answer to update automatically if input values change

• It hides the numbers from other users

• It prevents errors in calculations

If you encounter a complex problem and feel unsure how to proceed, what is the recommended approach?

• Give up and find a simpler problem

• Break the problem down into more manageable chunks

• Ask someone else to solve it for you

• Guess the answer and hope it's correct

A jet ski costs $6,000. If you save $110 each month, how many years will it take to save the full amount?

• 4.55 years

• 5.0 years

• 5.55 years

• 6.0 years

What was the first step taken to solve the jet ski savings problem in Excel?

• Calculate the total cost of the jet ski

• Determine the number of months in a year

• Calculate the total amount saved per year

• Find out how many jet skis can be bought

What formula was used to calculate the yearly savings for the jet ski?

• =B2+12

• =B2-12

• =B2*12

• =B2/12

If you save $110 per month, what is your total yearly savings?

• $1,100

• $1,200

• $1,320

• $1,440
