A= 308 miles
For this proplem you must use a proportion. You know that the automobile can travel 176 miles on 8 gallons of gas, so you could do 176 over 8 on one side of the equals sign and 14 across from 8 on the other side. x is the variable for the number of miles, so that would go across from 176. you cross multiply 176 and 14 to get 2464, then multiply 8 and x to get 8 x. In order to get x by itself, you must divide both sides by 8.
[tex] \frac{176}{8} = \frac{x}{14}
