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

Milan has a car that gets 30 miles per gallon. Her car has a 12 gallon tank. The function f(x) = 12(30) - 60x models how long Milan can drive until her tank is empty at 60 miles per hour. What are the domain and range of this situation?

• Domain: 0 < x < 360

  Range: 0 < y < 12

• Domain: 0 < x < 6

  Range: 0 < y < 360

• Domain: all real numbers

  Range: all real numbers

• Domain: 0 < x < 30

  Range: 0 < y < 60
