Answer:
- $5.058 USD/gal
- $60.70 USD to fill the tank
Step-by-step explanation:
You want to know the cost per gallon of gas and the cost for 12 gallons of gas when the cost per liter is $1.31 CDN and the exchange rate is $1.02 USD per CAD.
<h3>Cost per gallon</h3>
The conversion between liters and gallons is ...
1 US gallon = 3.785411784 liters (exactly)
Then the cost conversion is ...

The cost per gallon in terms of US dollars is about $5.06.
<h3>Cost per tank</h3>
The cost for 12 gallons will be ...
(12 gal)×($5.058 /gal) ≈ $60.70
It will cost you $60.70 to fill your 12 gallon tank.

<em>Additional comment</em>
The price of gas is routinely specified to tenths of a cent, both in the US and in Canada. As of today, the cost of gas in Canada has declined to $1.864 CAD/liter. At today's exchange rate of about $0.77 USD per CAD, the equivalent price is $5.406 USD/gal.
Step-by-step explanation:
ΔACX is an isosceles triangle, so ∠AXC = ∠XAC. We'll call the measure of this angle x°.
∠AXC and ∠BXC are supplementary, so ∠AXC + ∠BXC = 180. That means ∠BXC = 180 − x.
ΔBXC is an isosceles triangle, so ∠XBC = ∠XCB. We'll call the measure of this angle y°.
Angles of a triangle add up to 180, so:
y + y + (180 − x) = 180
2y = x
y = x/2
∠ACX and ∠XCB are complementary, so ∠ACX + ∠XCB = 90.
x + y = 90
x + x/2 = 90
3/2 x = 90
x = 60
Therefore, ∠AXC = ∠XAC = 60°.
