The table above gives the gasoline costs and consumption rates for a certain car driven at 50 miles per hour, using each of two brands of gasoline. How many miles farther can the car be driven at this speed on $12 worth of brand I gasoline than on $12 worth of brand Y gasoline?
Hello Karishma am totally confused on this question any efficient method?
Thank you

Again, In a manufacturing plant, it takes 36 machines 4 hours of continuous work to fill 8 standard orders. At this rate, how many hours of continuous work by 72 machines are required to fill 12 standard orders?
This how I solved it
36machines——8orders——4hrs
72machines——12orders—— Xhrs
Now,Xhrs=4*(72/36)*(12/8) =12hrs
But was wrong
multiplied by 72/36 since machine increased so fraction (>1) same applies to the orders, Where did my logic go wrong.
Also,when is it appropriate to use the chain rule W1/M*T= W2/M*T
