My truck gets 20 miles per gallon. Gas is $3.70 per gallon. Tell me how much gas will cost for the trip when the trip is 270 miles
First find the number of gallons by making this proportion

%28270%2Ami%29%2F%2820%2Ami%29 = %28x%2Agal%29%2F%281%2Agal%29

20x = 270

  x = 270%2F20
  
  x = 13.5 gallons


Then multiply by $3.70

(13.5)($3.70) = $49.95
