Answer:
<h3>Part A</h3>
<u>4 CD's cost $30.40, so one CD costs:</u>
- 4p = $30.40
- p = $30.40/4
- p = $7.60
<h3>Part B</h3>
80% of the regular price is $7.60
<u>If the regular price is r, we have:</u>
- 0.8r = $7.60
- r = $7.60/0.8
- r = $9.5
<u>3 CD's at regular price cost:</u>
Since $25 < $28.5, we can't buy 3 more CD's.
<h3>Part C</h3>
<h3>
Answer: Choice A. |w - q|</h3>
Let's say for example that w = 10 and q = 7. This means the distance between these values is w-q = 10-7 = 3. This is the distance between w and q.
Now let's make q larger. If w = 12 and q = 20, then w-q = 12-20 = -8 assuming we subtract in the same order. We use absolute value bars to ensure the result is positive. So instead we say
|w - q| = |12 - 20| = | -8 | = 8
Distance is never negative.
