The formula w = a + r x Int, where t represents the time in hours, w represents the amount of fresh water produced in thours, represents the
amount of fresh water produced in one hour and r is the rate of production, models the amount of fresh water produced from salt water during a
desalination process. In one desalination plant, 15 26 cubic yards of fresh water can be produced in one hour (a) with a rate of production of 312 (1)
Round answers to the nearest thousandth.
