The daily cost of hiring a plumber, y, to work x hours on a repair project can be modeled using a linear function. The plumber charges a fixed cost of $80 plus an additional cost of $45 per hour. The plumber works a maximum of 8 hours per day. For one day of work, what is the range of the function for this situation?
0 ≤ x ≤ 8
80 ≤ y ≤ 440
0 ≤ x ≤ 10
45 ≤ y ≤ 685
