Answer:
a) MARKUP PERCENT = 200%
b) <u>If the cost price of clothing A = $10</u>
then its retail price = $30
<u> If the cost price of clothing B = $25</u>
then its retail price = $75
Step-by-step explanation:
Let us assume the original price for the clothing = a
Now, boutique triples the price of the items it purchases for resale.
So, the resale value of the item of clothing = 3 times (Original price) = 3 a
So, here: The resale Value = 3 a
a) MARK UP Percentage =
or, the MARKUP PERCENT = 200%
b) Two expressions that represent retail price
<u>If the cost price of clothing A = $10</u>
then its retail price = 200% of 10 + 10 = 20 + 10 = $30
<u>If the cost price of clothing B = $25</u>
then its retail price = 200% of 25 + 25 = 50 + 25 = $75
Answer:
(x - 10)² + (y + 9)² = 20
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
The radius is the distance from the centre to a point on the circle
To calculate r use the distance formula
r = √(x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (10, - 9) and (x₂, y₂ ) = (12, - 13)
r =
= =
, hence
(x - 10)² + (y - (- 9))² = ()², that is
(x - 10)² + (y + 9)² = 20
