how do you solve this and what is the answer

Question

Harper is working two summer jobs, making $12 per hour babysitting and $8 per hour landscaping. Harper must earn no less than $140 this week. Write an inequality that would represent the possible values for the number of hours babysitting, bb, and the number of hours landscaping, ll, that Harper can work in a given week.

Answer 1

Let bb represent the number of hours Harper spends babysitting, and ll represent the number of hours Harper spends landscaping.

Given that Harper earns $12/hr babysitting, and $8/hr landscaping, we can write an equation representing Harper's earnings as:

Total earnings = 12bb + 8ll

Since Harper must earn no less than $140, we can write this as:

140 ≤ 12bb + 8ll

This inequality represents the possible values for the number of hours babysitting and landscaping that Harper can work in this given week.
