Answer:
B $12,500
Explanation:
The amount when data collection was first begun is the amount when the independent variable, x, is 0. This is also the y-intercept.
The equation for the model is in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept.
In this equation, the value for b is 12.5; this means that the amount at the start of data collection is 12.5(1000), or 12,500.
