A chair company produces two models of chairs, the Sequoia and the Saratoga. The Sequoia model takes 3 hours to assemble and 
hour to paint. The Saratoga model takes 2 hours to assemble and 1 hour to paint.The maximum number of hours available to assemble is 24 per day and the maximum number of hours available to paint is 8 per day.
(a)If the company earns a profit of $20 per Sequoia model and $30 per Saratoga model, find the number of models produced per day in order to maximize profit. (b)If the company earns a profit of $30 per Sequoia model and $15 per Saratoga model, find the number of models produced per day in order to maximize profit. (c)Suppose the company decides to upgrade the two models so it takes an additional 2 hours to detail the Sequoia and 2 hours to detail the Saratoga. The maximum number of hours available to detail is 18 per day. If the company earns a profit of $45 per Sequoia model and $35 per Saratoga model, find the number of models produced per day in order to maximize profit. (d)Suppose the company decides to upgrade the two models so it takes an additional 2 hours to detail the Sequoia and 2 hours to detail the Saratoga. The maximum number of hours available to detail is 18 per day. If the company earns a profit of $30 per Sequoia model and $40 per Saratoga model, find the number of models produced per day in order to maximize profit.
