Answer:
She should buy a total of 25, so one more can
We need to find a distance between this to points.
D=√((x2-x1)²+(y2-y1)²)
For complex plain, the real part of the complex number plays a role of x,
and number of an imaginary part plays a role of y.
So,
D=√((8-2)² +(7+1)²)√ = √(36+64)=√(100)=10
Answer is D.10
