Answer:
d
Step-by-step explanation:
the reasoning for this is because you count all the 2's and the little number in the corner and then you can't leave the 7 so you put the x7 for that reason
So the exchange rate from one US dollar to a Canadian dollar is equal to 1.30 Canadian dollars. So in this current situation if you swapped all of your US dollars for Canadian dollars you would have $13000 Canadian dollars
I think the answer is around 1.4 as you need to multiply the area by 1/9 after finding the real area.
