Answer 1

Solution:
	The cost per litre is C$ 1.00
Working Notes:	1 Gallon = 3.8 litres
	1 Gallon cost = US$ 3.84
	US$ 1 = C$ 0.99
So,
	For US$ 3.84 we get 3.8 litres
OR	3.8 litres = US$ 3.84
	1 litres = US$ 3.84/3.8
	1 litres = US$1.01052631578
	1 litres = US$ 1.010526
As we know	US$ 1 = C$ 0.99
So	US$ 1.010526 = C$ 0.99 x 1.010526
	US$ 1.010526 = C$ 1.00042074
Therefore
	1 litres = US$ 1.010526
	1 litres = C$ 1.00042074	putting US$ 1.010526 value in C$
	1 litres = C$ 1.00
	The cost per litre is C$ 1.00
