Asked by Cherie

A stock drops 30 points in five days. Use integers to find the new level of the stock. The stock started at 480 points.

I have been using a number line to shoe division but I am stuck on this one. Any help would be great.

if it was at 480, and dropped by 30, the new level is 480-30 = 450

If using the number line, moving right shows an increase, and moving left shows a decrease. So, start at 480, and move left by 30 to 450.
