Your answer is D.
The jeans are 40% off (because you add 20% more).
And the original cost of the jeans is $30.
You could have done:
30 · 0.40 = 12 (Find 40% of $30, then subtract 30 by 40% of 30 to get the new sale price]
30 - 12 = 18
1 - 0.40 = 0.60 (You subtract 1 by 0.40 to get 0.60, which is the % of the original price that you have to pay)
30 · 0.60 = 18
Answer:
C. 10
Step-by-step explanation:
it changes by positive ten each week
The answer is 27

The coordinates of the vertex for the quadratic function are given as follows: (100,10).
<h3>What is the vertex of a quadratic equation?</h3>
A quadratic equation is modeled by:

The vertex is given by:

In which:
In this problem, the function is given as follows:
y = -x²/1000 + x/5
y = -0.001x² + 0.2x.
Hence the coefficients are a = -0.001, b = 0.2, c = 0 and the coordinates of the vertex are given as follows:
