An employee who lives 35 miles from her place of work can either drive or take the subway. Use the following information to compare the relative costs of these two options:1. A monthly subway pass costs $65.2. Her car gets 24 miles per gallon of gas.3. The estimated cost of gas is $2.60 per gallon.4. She works an average of 22 days per month.How much would the employee save per month if she takes the subway? (Round to the nearest dollar.)

Respuesta :

For this problem, let's compute the monthly cost of using her car. The amount of gas is

[tex]\frac{(35mi)\cdot2\cdot22}{24\text{ mi/gal}}=64.17\text{gal}[/tex]

Therefore, she spends

[tex]64.17\text{ gal}\cdot(2.60\text{ dollars/gal)=}166.84\text{ dollars}[/tex]

Then, she will save $166.84-$65.00=$161.84, which is approximately $162.00.
