Jesse earns $18.50 per hour at his job. He works between 10 and 40 hours per week. The function y=18.5x for 10≤x≤40 shows the relationship between the hours worked and his weekly pay. What are the domain and range for this function?
Domain: 10 ≤ x ≤ 40; Range: 185 ≤ y ≤ 370
Domain: 10 ≤ x ≤ 40; Range: 185 ≤ y ≤ 740
Domain: 10 ≤ x ≤ 50; Range 185 ≤ y ≤ 925
Domain: 10 ≤ x ≤ 40; Range: 185 ≤ y ≤ 780
