Answer:
Step-by-step explanation:
If she is saving 1/5 of the original price, she is still paying 4/5, right? So the cost of the phone on sale is 700(4/5) which is $560.
She is then saving 10% on that sale price. But if she is saving 10%, she is still paying 90%, right? So the final cost of the phone is 560(.90) = $504
To find the total discount, subtract the final cost from the original:
700 - 504 = $196

Part A: What do the x-intercepts and maximum value of the graph represent? What are the intervals where the function is increasing and decreasing, and what do they
The 3-D shape would be created if the figure was rotated around the x-axis is a cone
<h3>What are 3-D shapes?</h3>
3-D shapes (short form of 3-Dimensional shapes) are shapes that have width, length and height
<h3>How to determine the 3-D shape?</h3>
The coordinates are given as:
(0, 0), (-3, -4) and (-3, 0)
When the above coordinates are plotted on a coordinate plane and the points are connected;
We can see that the points form a right-triangle
See attachment for the shape
As a general rule
Rotating a right-triangle across the x-axis would form a cone
Hence, the 3-D shape would be created if the figure was rotated around the x-axis is a cone

Answer:
We have to find the percent of change :
10 gallons to 24 gallons.
Original amount = 10 gallons
Final amount= 24 gallons.
Change in amount = 24 - 10 = 14 gallons.
then;
Substitute the given values we have;
Simplify:
Therefore, percent of change is, 140%
