Answer 1

First, let's find how many gallons are needed:

$\begin{gathered} \frac{286miles}{33\text{ }\frac{miles}{gallon}} \\ 8.7gallons \end{gathered}$

If the price of one gallon is $3.86, then they will have to pay:

$\begin{gathered} 3.86*8.7 \\ 33.58 \end{gathered}$

The price they will have to pay is $33.58.

Dividing the price by 3 (each student):

$\begin{gathered} \frac{33.58}{3} \\ 11.2 \end{gathered}$

Answer: Each student will have to pay $11.20.
