The median gasoline price is $1.84

The difference of the first and third quartiles in this set of gas prices is $0.34

Step-by-step explanation:

Let's order the seven gasoline prices given, this way:

$1.61, $1.75,  $1.79, $1.84, $1.96, $2.09, $2.11

Now, let's cut the list into quarters:

$1.61, $1.75,  

$1.79, $1.84, $1.96,

$2.09, $2.11

And the result is:  

Quartile 1 (Q1) = $1.75

Quartile 2 (Q2), which is also the Median, = $1.84

Quartile 3 (Q3) = $2.09

The median gasoline price is $1.84

The difference of the first and third quartiles in this set of gas prices is $ 0.34 (2.09 - 1.75)
