Let X = City MPG
Let X+6 = Highway MPG


462 Miles / x+6 MPG

336 Miles / x MPG

You can set the two equal because a tankful in the car will have an equal number of gallons.

336/x = 462/(x+6)

336x + 2016 = 462X

2016 = 126x

16 = x

ans. E

A/B = 2/5

(A+4)/2B= 1/3


2B = 5A
-2B =-3A - 12
_____________
0 = 2A -12
12 = 2A
A =6

Plug 6 back in to get B.

2B = 5(6)
2B = 30
B = 15

A + B = Sum of numerator and denominator
6 + 15 = 21
