Answer:
$ 15.00
Step-by-step explanation:
9.95 is JUST about 10
5.25 is close to 5
10 + 5 = 15
The percentage discount will be 9%.
<h3>How to calculate the value?</h3>
From the information given, the item he wants to buy is priced at $13, before discount and tax and after the discount, and before tax, the price is $11.83.
The percentage discount will be:
= (13 - 11.83)/13 × 100
= 1.17/13 × 100
= 9%
Therefore, the percentage discount will be 9%.

Answer:
(X2+3)2
Step-by-step explanation:
First, you have to substitute in what f(x) equals for y since f(x) stands for y.
By doing this, the equation turns into (x2+3)2, because x2+3 is y, and 2 because the original equation way y2.
After you substitute, the answer is (x2+3)2.
Answer:
18
Step-by-step explanation:
w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:
w = kz
When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:
12 = 4k
Dividing both sides by 4:
12/4 = 4k/4
k = 3
Therefore the equation becomes:
w = 3z
The value of w when z = 6 is given as:
w = 3(6)
w = 18
This is how the graph should look like
