Step-by-step explanation:
markup amount = 45% of $27
=> 45/100 * $27
=> $12.15
Now,
selling price = $27 + $12.15 => $39.15

Step-by-step explanation:
<u>Step 1: Define</u>
5x - 2 = 13
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 2 on both sides: 5x = 15
- Divide 5 on both sides: x = 3
Assuming imaginary numbers aren't possible the answer would be
x < -3
otherwise
x not= -8 and 2
The answer is C
162,383/11= 14762.09091
Answer:
7.17 cm
Step-by-step explanation:
Given that :
Mean (m) = 6.8 cm
Standard deviation (s) = 0.44 cm
Cut off value for the 80th percentile :
The cut off value :
From ;
Zscore = (x - m) / s
x = cut off value
Zscore corresponding to 80%(0.8) = 0.842 (from z probability calculator)
Plugging into our formula :
0.842 = (x - 6.8) / 0.44
0.842 * 0.44 = x - 6.8
0.37048 = x - 6.8
0.37048 + 6.8 = x
7.17048 = x
X = 7.17 cm
