Step-by-step explanation:
Given data
Initial cost =$28
Final cost =$36
Required
The percentage change in cost
Percent change =final - initial/initial*100

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out the maximum amount of profit the company can make, to the nearest dollar.
y=-x^2+90x-454
9514 1404 393
Answer:
$1571
Step-by-step explanation:
If we assume that y is profit in dollars, the maximum value of y is revealed by a graph to be ...
ymax = $1571
The maximum profit the company can make is $1571 at a selling price of $45 each.
_____
The function can be written in vertex form as ...
y = -(x^2 -90x) -454
y = -(x^2 -90x +45^2) -454 +45^2
y = -(x -45)^2 +1571
Because the leading coefficient is negative, we know this vertex represents a maximum. (x, y) = (45, 1571) at the vertex. Maximum profit is $1571.
expand x(x-6)
..........
Answer:
X² - 6x
Step by step:
Times x by x which makes x², then x times 6 makes 6x.
You get your finally answer x²-6x

Edwin bought 3 cds and 7 dvd for $80 Jessica bought 6cds and 3 dvds for $63.75 which system of equation could be used to determine how much one cd and one dvd cost
Answer:
The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.
Step-by-step explanation:
Given that:
Cost of 3 CDs and 7 DVDs = $80
Cost of 6 CDs and 3 DVDs = $63.75
Let,
x be the cost of one CD
y be the cost of one DVD
According to given statement;
3x + 7y = 80
6x + 3y = 63.75
Hence,
The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she should put into each bag?
Answer:
Softballs = (48/b)
Step-by-step explanation:
Given that,
Total number of softballs = 48
She wants to divide them evenly among b softball bags.
We need to find an expression that represents how many softballs she should put into each bag.
As it is dividing among b softball, it means we divide 48 and b. So,
[tex]s=\dfrac{48}{b}[/tex]
Hence, the required expression is (48/b).

Answer:
A, commutative
Step-by-step explanation:
Commutative property means that you can switch around the numbers, and get the same answer. However, the commutative property is only compatible for addition and multiplication. I.e. 2+6 equals 6+2, but 2-6 does not equal 6-2.
