Jackson runs a farm stand that sells bananas and grapes. Each pound of bananas sells for $1 and each pound of grapes sells for $2.25. Jackson sold 15 more pounds of
bananas than pounds of grapes and made $54 altogether. Graphically solve a system
of equations in order to determine the number of pounds of bananas sold, x, and the
number of pounds of grapes sold, y.

At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 16 cubic feet per minute. the diameter of the base of the cone is approximately three times the altitude. at what rate is the height of the pile changing when the pile is 12 feet high? (hint: the formula for the volume of a cone is v = 1 3 πr2h.)
