The Howard family and the Watson family each used their sprinklers last summer. The Howard family's sprinkler was used for 30 hours. The Watson family'ssprinkler was used for 35 hours. There was a combined total output of 1650 L of water. What was the water output rate for each sprinkler if the sum of the tworates was 50 L per hour?Note that the ALEKS graphing calculator can be used to make computations easier.
