PLEASE HELP!!!

The inequality that represents the steps taken after the first day is 2000 + 500x ≥ 10000

<h3>Part A: The inequality that represents the number of steps?</h3>

The given parameters are:

  • Initial number of steps = 2000
  • Rate each day = 500
  • Total number of steps = At least 10000

In inequality, at least means greater than or equal to i.e. ≥.

So, the inequality that represents the number of step each day (x) after the first day is:

2000 + 500 * x ≥ 10000

This gives

2000 + 500x ≥ 10000

<h3>Part B: How to exceed the goal</h3>

To exceed the goal faster, Angel can do any of the following activities:

  • Increase the initial number of steps from 2000 to (say) 2500. This is represented by 2500 + 500x ≥ 10000
  • Increase the rate from 500 to (say) 600. This is represented by 2000 + 600x ≥ 10000
