Answer:
Amplitude = 4
Step-by-step explanation:
The general form of a sine curve would be 
where A is the <u>"amplitude"</u>, or the "tallness" or "shortness" of the graph.
Technically, amplitude is the absolute value of the number that is multiplied in front of "Sin". So the amplitude is 4.
<u>Note:</u> The negative sign in front of 4 plays the role of "flipping" the curve upside down.
Greetings!
An item at full price is 100%, or by using the percentage formula: 
If something is at 30% off, that means it is 70% of the original price (because minus the percentage from the 100%)
So by substituting the numbers into the percentage formula you end up with:
which is 0.7
So your answer would be D, 0.7!
Hope this helps!
