The total amount after 5 years would be $2,650
Direct variation is of the form y=kx (inverse variation is of the form y=k/x)
Whenever you reflect a point over the x axis, the x coordinate stays the same and the y coordinate is negated. In this case, the y coordinate which is 3 will be negated to become -3, and the x coordinate which is -5 will remain the same. Therefore, the new point is (-5,-3).
I hope this helps.
