Question

Suppose that premium gasoline is selling for about $2.98 a gallon using the fact that 1L equals 1.057 quarts. determine the price of the gasoline in dollars per liter?

Answer 1

The price would be `78.7` `c` per litre.

(As a side note, currently in Australia we're paying about twice that.)

Explanation:

Working across unit systems, the fact that there are `4` quarts in a gallon is also relevant.

`1` `L`, then, will be `1.057/4=0.2643` gallons.

The price per litre will be `0.2643xx$2.98=$0.787=78.7` `c`.
