document.write( "Question 1152496: Dry Boat Works wholesales aluminum boats for $200 and fiberglass boats for $150. Northland Marina wants to order at least $600 worth but no more than $1,200 worth of boats from them. Graph a system of inequalities that will show the possible combinations of the number of aluminum boats (x) and the number of fiberglass boats (y) that can be ordered.

here's the graph.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "anything in the area that's not shaded is possible.
\n" ); document.write( "also anything on the lines that enclose the non shaded area are posible since the inequality includes equal as well (<= not <)(>= not >).
\n" ); document.write( "the points that fit the requirements have been noted.
\n" ); document.write( "they are shown in (x,y) format.
\n" ); document.write( "the inequality is 600 <= 200x + 150y <= 1200
\n" ); document.write( "for example, the point (3,4) is possible since 200 * 3 + 150 * 4 = 600 + 600 = 1200 which is the upper limit of what's possible.
\n" ); document.write( "likewise, the point (0,4) is possible since 200 * 0 + 150 * 4 = 600 which is the lower limit possible.
\n" ); document.write( "likewise, the point (2,4) is possible since 200 * 2 + 150 * 4 = 400 + 600 = 1000 which is above 600 and less than 1200.
\n" ); document.write( "the value of x and y have to be integers since only whole boats can be sold.\r
