Question 3 A. Scholes is a small computer and supplies company specializing in XP pens and computers they sell to teachers. After 25 years in operation, the company has developed a profit function, 5(x,y)=-3x² - 4y² + 4xy-2x + 12y-4 in millions of dollars. Let x represents the number of XP pens and y represents the number of computers. i. Determine the number of XP pens (per 1000) and computers (per 1000) that should be sold to maximise this cost. ii. What is the maximum cost?
