Translate the sentence into a mathematical equation. Be sure to identify the meaning of all symbols.The profit derived from the sale of x video cameras is $350 per unit less the sum of $2000 costs plus $150 per unit.
A. If P is profit and x the units sold, then P = 350x + 2000 - 150x or 
B. If P is profit and x the units sold, then P = 
- (2000 + 
) or 
C. If P is profit and x the units sold, then P = 350x - (2000 + 150x) or 
D. If P is profit and x the units sold, then P = 350x - (2000 - 150x) or
