Question 4

Explanation:

Step1: Calculate daily miles

The commute is 10 miles each way, so daily miles are $10\times2 = 20$ miles.

Step2: Calculate weekly miles

You work 5 days a week, so weekly miles are $20\times5=100$ miles.

Step3: Calculate monthly miles

In a 4 - week month, monthly miles are $100\times4 = 400$ miles.

Step4: Calculate gallons of gas used

The car gets 30 miles per gallon. So the number of gallons of gas used is $\frac{400}{30}=\frac{40}{3}$ gallons.

Step5: Calculate cost of gas

Gas costs $4.25$ per gallon. So the cost is $4.25\times\frac{40}{3}=\frac{170}{3}\approx56.67\approx57$ dollars.

Answer:

about $57$
