The original cost is $19.55
Step-by-step explanation:
What we want to do here is calculate the final cost, given the original price
What we have to do here is to substitute the value of $23 for p

Step-by-step explanation:
AB=BD
BC=2CD --> CD=1/3 BD
--> AD= 6CD
a) see attachment for graph
b) D: [0, 2.5] <em>time cannot be negative so the x-values start at 0</em>
R: [0, 100] <em>height cannot be negative so the y-values start at 0</em>
c) 84 ft <em>refer to the red coordinate on the graph</em>
d) 1.75 seconds <em>refer to the blue coordinate on the graph</em>
e) 2.5 seconds <em>refer to the green coordinate on the graph</em>
<em />
When looking for coordinates at the various given values, remember that x is time and y is height.
- If you are given time, then look at the y-value for height
- If you are given height, then look at the x-value for the time.
