Gas is $2.53⁹ per gallon today, at that filling station
down the street from my house.
I have $10 in my pocket.

a). How much gas can I put in the car if I go there ?

b). My car gets 25 miles per gallon. How many 'miles' will my $10 buy ?

c). In Calgary (Alberta, Canada) today, gas is selling for
89¢ (Canadian) per liter. What is the percentage more or less,
compared to the price of gas down the street from my house ?

If I posted this problem on Brainly, I'd probably give it
something like 5 points for part-a, another 5 for part-b,
and 10 or 15 for part-c because in addition to math,
that part takes some research.
