A construction crew is pouring concrete to make a floor in a building. The weight, w, of the a
concrete is proportional to the volume of concrete, v, that has been poured. After pouring 5
cubic feet, they know the weight of the concrete is 740 pounds.
(a) If the construction crew uses a total of 12 (b) The crew wants to create an equation of
cubic feet of concrete, set up and solve a the form w=k-y to calculate the weight,
proportion for the amount the concrete w, of the concrete based on its volume, v,
weighs, w.
in cubic feet. What is the value of k in this
equation? Explain.
