Question

In one U.S. city, the taxi cost is $5 plus $0.70 per mile. If you are traveling from the airport, there is an additional charge of $5.00 for tolls. How far can you travel from the airport by taxi for $45.00? You can travel

Answer 1

You have $45

After discount the fixed $5 and the charge for tolls, $45 - $5 - $5 = $35 are left.

1 mile cost $0.70. To find how many miles you can travel with $35, we can use the next proportion:

$\frac{0.70\text{ \ }}{35\text{ \ }}=\frac{1\text{ mile}}{x\text{ mile}}$

Solving for x

$\begin{gathered} 0.70\cdot x=1\cdot35 \\ x=\frac{35}{0.70} \\ x=50\text{ miles} \end{gathered}$

You can travel 50 miles from the airport
