Answer:
The inequality that represents the given situation is 12b + 7w ≥ 55
Step-by-step explanation:
Let us solve the question
∵ Savannah is working two summer jobs
∵ She is making $12 per hour babysitting
∵ The number of hours babysitting is b
→ Multiply 12 by b to find the amount earning from babysitting
∴ She is making 12b dollars from working as a babysitting
∵ She is making $7 per hour washing cars
∵ The number of hours washing cars is w
→ Multiply 7 by w to find the amount earning from washing cars
∴ She is making 7w dollars from working in washing cars
∵ Savannah must earn a minimum of $55 this week
→ minimum means ≥,
∴ The total earning ≥ 55
∵ The total earning is 12b + 7w
→ Use the two expressions of the total earning to write the inequality
∴ 12b + 7w ≥ 55
∴ The inequality that represents the given situation is 12b + 7w ≥ 55
