Q. According to his running log, Edmond averaged 33 miles per week this month, which is 70%70\% less than last month. How much did he average last month?\newline____ miles
  1. Understand the problem: Step 11: Understand the problem and set up the equation.\newlineEdmond ran 33 miles per week this month, which is 70%70\% less than last month. We need to find out how much he ran last month. Let's denote last month's average as xx miles per week.\newlineCalculation: 3=0.30x3 = 0.30x (since 70%70\% less means he ran 30%30\% of last month's mileage this month).
  2. Set up the equation: Step 22: Solve for xx.\newlineDivide both sides of the equation by 0.300.30 to isolate xx.\newlineCalculation: x=30.30x = \frac{3}{0.30}\newlinex=10x = 10 miles per week.
