How many dollars will it cost to run the car for 100 miles? (A) (g + m)/100 (B) 100g + 100m (C) g + m (D) g + .1m (E) g Let g=200 cents, implying that the gas cost per mile =$2.
Let m=300 cents, implying that the gas cost per mile = $3. Total cost per mile = 2+3 =$5.
Thus, the total cost for 100 miles = 100*5 = $500. Since the question stem asks for the cost, in dollars, for 100 miles, the target value is 500. Now plug g=200 and m=300 into the answers to see which yields the target value of 500. Only C works: g + m = 200+300 = 500. The correct answer is C. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.

Gasoline cost: g cents/mile for 100 miles = 100g cents Other costs: m cents/mile for 100 miles = 100m cents Total cost: (100g + 100m) cents, or g + m dollars. (There are 100 cents in 1 dollar) The answer is C. _________________ Veritas Prep | GMAT Instructor Veritas Prep Reviews Save$100 off any live Veritas Prep GMAT Course
