Answer:
dy/dx = 2/x
Step-by-step explanation:
y = In x^2
Let u = x^2
du/dx = 2x
y = In u
dy/du = 1/u
dy/dx = dy/du × du/dx = 1/u × 2x = 1/x^2 × 2x = 2/x
Let the original price be x . And the stores are offereing 20% discount. It means , we need to pay only 80 percent.
And it is given that the discount prices is 16.80. That is
0.8x = 16.80
Now we need to get rid of 0.8.
And for that, we divide both sides by0.8,
x =21
So the original price is $21 .
