A play station costs $500, but you want to only pay $450. How much discount in percents do you want?

Alexus [3.1K]

Answer:

You only want a 10% discount...

500 - 450 = 50

50/500 = 1/10 = .1 = 10%

I need help with this

Answer:

Step-by-step explanation:

The domain is the horizontal extent of the graph. The graph extends to infinity in both directions horizontally (that's what the arrows mean). There are no "holes" because the open circle at x=-1 is matched by a filled circle at the same location.

The range is the vertical extent of the graph. The minimum is -3, which is included in the range. The maximum is infinity (as indicated by the up-pointing arrow).
