Answer:

70 miles driven this month

Step-by-step explanation:

This is an algebra problem and denote A number of miles driven this month as x to be found

  • 30 % decrease of x number of miles for this month
  • last month miles driven = 100 %
  • then 100 % /100% * 100 miles = 100 miles
  • thus this month = 100 % - 30 % = 70 %
  • then for this month in miles =  70 %/ 100 % * 100 miles = 70 miles
