A trades worker has a job in a large city. she can aither rent an apartment in the city for $ 1400 per month or a comparableone in the suburbs for $1200 per month. If she lives in the city , she can walk or bike to work. If she lives in the suburbs, she must drive 60 miles per day round- trip an average of 22 days per month. Her car averages 24mi/gal and gas cost $3.50 per gallon. If she decides to live in the suburbs, would the total monthly cost of gas be more or less than the savings in rent?

Solution

There is no expenditure if he lives in the city, since he can walk to the work

Monthly Rent in City = 1400$

Monthyl Rent in Suburbs = 1200$

Savings = 1400-1200 = 200$

Distance he has to travel by car = 60 miles * 22 = 1320 miles

The car averages 24 miles/gallon

Amount of Gas required in Gallon = 1320 miles/ 24 miles/gallon = 55 gallon

Cost of 1 gallon = $3.50

Cost of 55 gallons = $3.50 * 55 = $192.50

If he lives in the suburbs then total cost = rent + gas cost = 1200 + 192.50 = $1392.50

If he lives in the city, then he has to spend more 7.5$ including the rent + gas cost in suburbs
