Question

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)
