Answer:

Since the measurement can't be negative the correct answer for this case would be 
Step-by-step explanation:
Let's assume that the figure attached illustrate the situation.
For this case the we know that the original area given by:

And we know that the initial area is a half of the entire area in red
, so then:

And we know that the area for a rectangular pieces is the length multiplied by the width so we have this:

We multiply both terms using algebra and the distributive property and we got:

And we can rewrite the expression like this:

And we can solve this using the quadratic formula given by:

Where
if we replace we got:

And the two possible solutions are then:

Since the measurement can't be negative the correct answer for this case would be

Answer:
The answer is option C=150%
Step-by-step explanation:
Original cost of the jacket=$16 in January
Final cost of jacket=$24 in September
What percentage must of the original price is the new?
The new price=the original price×(A percentage)
Where the new price=$24, the original price=$16, and the percentage=(x/100)
24=16×x/100
x=(24×100)/16=150%
The answer is 150%
