The speed one (c) is a red herring. Nothing we can see measures her speed.

The only graph that could possibly represent the right answer is D (first graph from the right). It shows that she topped 1/2 way up. It also shows that she took her time about coming down when she was at the top.

The only thing we don't know is A. What's on the vertical axis?

KatRina [158]

To find the total from the percent part you have, you divide the part by the percentage.
1.50÷0.05=30
The total is $30
The total the store charged, including sales tax, is $31.50.
