7 The graph of p = 400 and the graph of p = 50s - 200 intersect at the point (12,400).
If the equation p = 50s - 200 represents the profit, p, based on s sales, what does
the intersection best represent?
A When the sales are 400, the profit is 12.
B When the sales are 12, the profit is 400.
C The profit is always 400.
D The sales are always 12.
