In a factory, the production hours t and output y are having linear relationship. When the
factory operates for 5 hours per day, it may have the number of outputs of 2000 units and 3500
units for 8 hours of operation.
(a) Model an equation that gives the outputs, y, in terms of operation hours, t, per day.
(b) If the factory wants to have 4500 units of production per day, how long it should operate?
(c) Draw the graph in excel of the production against operation hours t up to first 20 hours.
