Final answer:
To find out how much 1.2 gallons of gas would cost, set up a proportion and solve for the unknown. The cost of 1.2 gallons of gas is $365.664.
Step-by-step explanation:
To find out how much 1.2 gallons of gas would cost, we need to set up a proportion using the given information. We know that 0.5 gallon of gas costs $304.72, so we can set up the proportion:
(0.5 gallon)/(cost) = (1.2 gallons)/x
Cross-multiplying, we get:
0.5x = 304.72 * 1.2
Simplifying, we find that x = $365.664, which means that 1.2 gallons of gas would cost $365.664.
