Answer:
the percentage profit is 20%
Step-by-step explanation:
Given that
Sean paid £10 for 24 chocolate bars
He sold all 24 chocolate bars for 50p each
we need to find out the percentage profit
Since he paid £10 and sale value is (24 × 0.50) i.e. £12
So, the percentage profit is
= (£12 - £10) ÷ (£10)
= 20%
Hence, the percentage profit is 20%
X=48 degrees
You find the missing degrees in the top triangle. Then you take that degrees and put it in the blank spot right across from the top triangle. To find x you take 180-33=147. The missing degrees was 99 so you take 147-99 and you get 48. You use 180 because that’s the degrees of a whole triangle.
Y= -5/2x - 3
because if parallel slope need to be the same and then it’s
-1 = -5/2(-4)+ b
-1 = 2 + b
b = -3
Then rewrite equation as y= -5/2x -3
