Answer:
Yes He should stop for Gas
Step-by-step explanation:
Step one:
given data
total distance left=429.5miles
we want to find the amount of gallons the car will consume for 429.5 miles
we are told that for 33 miles traveled the car will consume 1 gallon of gas
hence for 429.5 miles the car will consume x gallons
cross multiply we have
x=429.5/33
x=13.0gallons
This shows that the tank will be empty for a 429.5 miles.
A.) Both services will cost the same if it is for a 3 hours service.
B.) 16+9X=20+7X.
=>9x-7x=20-16.
=>2x=4.
=>x=4/2.
=>x= 2.
whats the Question!??
