Evaluate the expression you wrote to find the amount ms.perkins will pay if she drives 300 miles.

Answer 1

if her vehicle gets x mpg

and gas costs y dollars per gallon

then going z=300 miles will cost her

C=yz/x = 300y/x dollars

for example, if the car gets 25 mpg (miles per gallon)

and gasoline costs $4 per gallon

she will need 300/25= 12 gallons

that costs 4(12)= $48 for the 300 mile trip

C = 300y/x = 300(4)/25 = $48

try another example. she gets 30 miles per gallon and gas costs $5 per gallon then cost =

C = 300y/x = 300(5)/30 = $50

not counting toll roads, stops for food, oil or other transportation expenses, depreciation on the vehicle, auto insurance, traffic tickets, flat tires, towing and more. if she has an accident it can get very expensive

The y value varies depending on city traffic or non stop highway driving. the x value varies en route at different gas stations. You could also add in social costs, negative externalities in economics lingo, as the climate change is a social cost not captured in the market cost of driving a fossil fuel vehicle.

If it's an EV vehicle you need more information about electricity and recharging costs, and a different equation. Plus if you have mechanical problems, no repair shop knows how to repair it. Even the insurance company may call it a total loss, even if it's a seemingly minor problem as they can't get parts for it.

either way, if Ms. Perkins is driving with a BAC over .08, her goose is cooked, police will arrest her and endless costs may bankrupt her, bail bond, higher prohibitive insurance premiums, court fines and fees, jail time, other driver suing her if there's an accident and winning, rehab costs, lose her job, ... she's toast

or if Ms. Perkins is black, driving through white male supremacist areas, police will pull her over no matter how super well she drives, so costs go through the roof and into the stratosphere
