Eggs are bought for 80c each and sold for R15 per dozen. What is the percentage profit (rounded off to the nearest percentage) ma
Mekhanik [1.2K]

The percentage profit made on the eggs is 56.25%

Data;

  • Cost price = 80c
  • Number of eggs = 1 dozen = 12 eggs
  • Selling price = R15

<h3>Percentage Profit</h3>

This is the ratio between the profit to the cost price multiplied by 100.

But 1 R = 100 cents

15 R = x

1R = 100c\\15R = x\\x = 15 * 100\\x = 1500c

The Cost price for 1 dozen is

80 * 12 = 960c

The cost price of the eggs is 960c

The percentage profit here will be

\% profit = \frac{selling price - cost price}{cost price} * 100\\\% profit= \frac{1500-960}{960}*100\\ \%profit = \frac{540}{960}*100\\ \% profit= 56.25 \%

The percentage profit made on the eggs is 56.25%

Write an equation of a line parallel to the line y=-2x+8 and passes through the point (-1,-3)​
saul85 [17]

Answer: y=–2x–5

Step-by-step explanation:

The equation of a straight line:

y=mx+c

m must be the same for the two lines to be parallel.

y=mx+c

y=–2x+8 → m=–2

For a new equation:

x=–1, y=–3, m=–2, c=?

y=mx+c → –3=–2×(–1)+c

–3=2+c

c=–5

So:

y=–2x–5
