Question

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge?

Answer 1

The expression that correctly shows the total of steps Eric needs to walk is y = -6,000x + 24,000.

How to write a mathematical expression?

• Identify the factors or variables involved.
• Use leters to represent unknown factors.
• Use +,-, etc. to show how the factors relate.

What is the best mathematical expression?

• x = number of days
• y = steps missing
• 24,000 = total steps
• 6,000 = steps per day

Based on this the best expression is

• y = -6,000x + 24,000

or the missing steps are equal to the number of days multiplied by the steps per day and subtracted to the total steps.
