Answer:
Charlene earns $700 per week
Kristi earns $550 per week
Sascha earns $800 per week
Step-by-step explanation:
Since Kristi earns 150 less than Charlene which is 100 less than Sascha, this is equal to the value of Sascha minus 250. We put this in the equation as s-250.
Together, they all earn $2050, so we must equal this to Charlene's value k+150, plus Kristi's value k, plus Sascha's value s.
<em>k+150+k+s=2050</em>
The next step here is to put the variables on one side and to put the numeric values on the other.
2k+s=1900
Like we said before, Kristi's value is equal to s-250, so we would replace k with that expression.
2(s-250)+s=1900
2s-500+s=1900
3s=2400
s= 800
We now have Sandra's weekly pay, which we can use to find the others' pay.
c= s-100
c= 800-100
c= 700
k= c-150
k= 700-150
k= 550
We don't know what the question is.
It could be "What is the selling price ?"
If that's the question, then . . .
Since the store marks up their cost by 60% before they sell
the thing, the price they sell it for is
(1.60 of their cost).
You know their cost. The selling price is (1.60 x $80) .
In order to develop an equation, let's use the slope-intercept form of the linear equation:

Using the points (3, 13.5) and (5, 18.5) from the table, we have:

Subtracting the second and the first equation:

Now, finding the value of b:

So the equation that represents this table is y = 2.5x + 6
Looking at the options, the correct one is E (none of the above).
Answer: width is 12, length is 16
Step-by-step explanation:
A= l*w
l=w+4
A=w(w+4)

factor
(w+16)(w-12)
w= -16 or w=12
width is 12, length is 16
