Hello!
In a taxi cab, the longer you ride, the more it costs. This would make a scatter plot go through Quadrant 1.
Therefore, it would have a positive relationship
I hope this helps!
If there are 15 nickels which is $0.75 and 12 dimes which is $1.20, then that would equal $1.95 and be 27 coins.
The answer to this problem would be 2.5.
