Write a system of inequalities that describes the possible solutions to the problem.The Pen-Ink Company manufactures two ballpoint pens: silver and gold. The silver requires 8 minutes in a grinder and 9 minutes in a bonder. The gold requires 14 minutes in a grinder and 9 minutes in a bonder. The grinder can be run no more than 550 minutes per day and the bonder no more than 260 minutes per day. Let x represent the number of silver pens, and let y represent the number of gold pens. Including the system inequalities 
and 
, find the remaining inequalities that best
represent this company's daily production of silver and gold pens.
A. 8x + 9y ? 550, 14x + 9y ? 260
B. x + y ? 550, x + y ? 260, x + y ? 810
C. 8x + 14y ? 550, 9x + 9y ? 260
D. 0 ? 17x + 23y ? 810
