Answer 1

Answer:

$3.50

Step-by-step explanation:

Let x be the cost of per gallon gas.

We have been given that it costs Raquel 5$ in tolls to drive to work and back each day, plus she uses 3 gallons of gas. It costs her a total of 15.50$ to drive to work and back each day.

We can represent this information as:

$3x+5=15.50$

$3x+5-5=15.50-5$  

$3x=10.50$    

$x=\frac{10.50}{3}$

$x=3.50$  

Therefore, Raquel is paying $3.50 for per gallon gas.
