Answer:
the price sold per kg to earn a profit of 20% is 7.2 kg
Step-by-step explanation:
The computation of the price sold per kg to earn a profit of 20% is shown below:
But before that the normal price per kg is
= 5.4 per kg × 100 ÷ 90
= 6 per kg
Now for 20% profit, the price per kg is
= 6 × (1 + 0.20)
= 6 + 1.2
= 7.2 kg
hence, the price sold per kg to earn a profit of 20% is 7.2 kg
Answer:
The area of a circle with a diameter of 10 inches is 78.5 in².
Step-by-step explanation:
1. Know the formula for finding the area of a circle.
A = r²
2. Since you need the radius for finding area, you will need to divide 10 by 2 because the radius is half of the diameter.
10 ÷ 2 = 5
3. Add in your numbers to the formula.
A = (5)²
4. Simplify the equation. We can use 3.14 for pi.
A = 25
A = 78.5
So, the area of the circle is 78.5 in².
