Answer:
D) 130 workers
Step-by-step explanation:
We have the equation, y = 2x + 40, and y, 300 (since the y-coordinate represents the # of bottles made), so we can solve for x, the number of workers needed.
Substitute: 300 = 2x + 40
Subtract: 260 = 2x
Divide: x = 130
Since x = 130 when y = 300, 130 workers are required to make 300 bottles in a day.
