Answer:
<u>25%</u>
Step-by-step explanation:
A department store buys 400 shirts at a cost of $6,400 and sells them at a selling price of $20 each. Find the percent markup.
I couldn't seem to calculate: A department store buys 500 shirts at a cost of $12,000 and sells them at a selling price of $30 each.
Find the percent markup
The percent markup is % (Round to the nearest whole number as needed.)
Answer:
C
Step-by-step explanation:
|2x - 2| < 8
it implies that
2x - 2 < 8
2x -2 + 2 < 8 + 2
2x < 10
x < 5
or
-(2x - 2) < 8
-2x + 2 < 8
-2x + 2 - 2 < 8 - 2
- 2x < 6
x > -3 ( the sense of the inequality reverse because I divided by minus)
The solution can be combine to
-3<x<5
Apply the Pythagorean Theorem here.
Square the lengths of the 2 shorter sides: (20 mi)^2 and (40 mi)^2. Correct results are 400 and 1600. Combine these: obtain 2000.
Then the length of the diagonal (which is the distance between the 2 cities) is
sqrt(2000) = sqrt(400)*sqrt(5) = 20 sqrt(5) (answer)
First find the slope using (y1-y2)/(x1-x2)
(-2-4)/(5+16) = -6/21 or -2/7
Then plug in one of the points into y-y=m(x-x)
y + 2 = (-2/7)(x - 5)
Distribute the slope.
y + 2 = -2x/7 + 10/7
Subtract 2
y = -2x/7 - 4/7
So the answer is A.
To solve for q subtract 2/3 from both sides:
(1/2-2/3)=q+(2/3-2/3)
(-1/6)=q
q= -1/6
I hope this helped!!
