79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100
100-12 = 98
We have to figure out what 88% is
79.30 ---- 100%
X ------------ 88%
Cross Multiply
79.3× 88 = 100x
6978.4 = 100X
69.784 is without taxes
69.784 = 100% {100% because it is the total price.}
69.784 = 100%
X --------- 6.25%
Cross Multiply
69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615
69.784 + 4.3615
74.15 is the answer
We want to find

, for

.
Recall the product rule: for 2 differentiable functions f and g, the derivative of their product is as follows:

.
Thus,
![y'=[(x^2+2)^3]'[(x^3+3)^2]+[(x^3+3)^2]'[(x^2+2)^3]\\\\ =3(x^2+2)^2(x^3+3)^2+2(x^3+3)(x^2+2)^3](https://tex.z-dn.net/?f=y%27%3D%5B%28x%5E2%2B2%29%5E3%5D%27%5B%28x%5E3%2B3%29%5E2%5D%2B%5B%28x%5E3%2B3%29%5E2%5D%27%5B%28x%5E2%2B2%29%5E3%5D%5C%5C%5C%5C%20%3D3%28x%5E2%2B2%29%5E2%28x%5E3%2B3%29%5E2%2B2%28x%5E3%2B3%29%28x%5E2%2B2%29%5E3)
Answer: A)

The answer is....<span>2 × 7 × 11.</span>
I think maybe 3) would make the most sense because she wants a random sample of students and the other options are specific on the type of students.
0.0900-0.0088=0.0812
I did it by thinking of it as 900-88=812
