The regular price is $22.5 if everything in a store is 20% off, and the discounted price of an item is $18.00
<h3>What is the percentage?</h3>
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
If everything in a store is 20% off, and the discounted price of an item is $18.00
Let's suppose the regular price is x
(100-20)% of x = 18
80x/100 = 18
x = $22.5
Thus, the regular price is $22.5 if everything in a store is 20% off, and the discounted price of an item is $18.00

Answer:
b
Step-by-step explanation:
Area of a rectangle = length x width
length = 8 + 2 = 10
width = 10 + 2 = 12
10 x 12 = 120
Answer:
8x²+6x+12xy+9y
Step-by-step explanation:
⇒(-2x - 3y)(-4x - 3)
⇒(-2x × -4x)+(-2x × -3)+(-3y × -4x)+(-3y × -3)
⇒8x²+6x+12xy+9y
Answer:
.25 or 1/4
Step-by-step explanation:
to find gradient/ slope,
choose any two points on line and divide the difference in y- values over difference in x- values
i.e. (0, 1), (10, 3.5)
2.5/10=.25 or 1/4
One mole is equal to 
atoms.
We will use unitary method that says unitary method is a process used to solve a situation by finding the value of a single unit, (by dividing) and then finding the necessary value by multiplying the single unit value.
Now we need to know how many moles are there in 
atoms make 1 mole
1 atom makes 
mole
Therefore,
atoms will make
moles.
Therefore, atoms make 1.328 moles.
