Jackie needs to earn at least $500 during the summer months. she babysits for $12 per hour and teaches swimming lessons for $20 per hour. due to her summer school class, she can only work 30 hours or less per week. let b equal the number of hours she babysits and s equal the number of hours she teaches swimming lessons. which set of inequalities model this situation?

Answers

  1. The set of inequalities that model this situation: 12b + 20s ≤ 30

    What is an inequality?

    Inequality refers to a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
    Now,
    Given:
    • Number of hours Jackie babysits = b
    • Number of hours Jackie teaches swimming lessons = s
    • Money earned for each hour of babysitting = $12
    • Money earned for each hour of swimming lesson = $20
    • Hours she can work in a week = 30
    The inequality that represents this situation:
    12b + 20s ≤ 30
    (where,
    1. 12b = Total amount of money earned for ‘b’ hours of babysitting,
    2. 20s = Total amount of money earned for ‘s’ hours of swimming lessons)
