To first solve this problem, we have to set up ratios based on the data given. First, we know that the dishwasher use rate is 700 watts/run. Next, we know 1 hr/run. Finally, we know there are 150 runs/year. To calculate how much energy per year, we arrange the ratios to give a final answer of watts/year. Doing this we get the following: 150 runs/year * 700 watts/run = 105,000 watts/year which is also equal to 105 kw/year. The ration of 1 hour per run does not make a difference in this question and is not needed for the final answer.
