Here, we want to select the option that best describes the commission earned;
In the question, we are told that the commission is a certain percentage variable on the amount of her sales;
Thus , mathematically to get the percentage commission, we simply need to have;
p(x) of f(x)
This simply refer to placing f(x) into p(x) which can be rewritten as ;

The closest answer to this is the first option A
Answer:
= y^2 -18y +81
Step-by-step explanation:
(y–9)^2
(y-9) (y-9)
FOIL
first: y*y = y^2
outer: -9y
inner: -9y
last: -9*-9 = 81
Add them all together = y^2 -9y-9y+81
= y^2 -18y +81
Answer: $34.75
Step-by-step explanation:
n= 6.25x+3.50
n=6.25(5)+3.50
n=31.25+3.50
n=34.75
We are given equation: c=6.4w, where the cost c for w pounds of walnuts.
w represents the number of pounds of walnuts.
Number of pounds could be in decimals.
The value of w = 2.5 represents 2.5 pounds of walnuts.
On plugging w=2.5 in c=6.4w equation, we get.
c=6.4×2.5 = $16.
Therefore, for 2.5 pounds of walnuts the total cost is $16.
Hence, <u>a value of 2.5 for w make sense in this situation. It shows that cost of 2.5 pounds of walnuts is $16, where cost of each pound of walnuts is 6.4.</u>
The total amount of the purchase was ...
... $2.50 + 3c = $5.05
This equation can be solved by subtracting 2.50 and dividing by 3. Both these operations are done to both sides of the equation in accordance with the rules of equality.
... 3c = $2.55
... c = $0.85
The cost of a bag of chips was $0.85.
