Answer:
see attached
Step-by-step explanation:
To find the inverse function, solve ...
x = f(y)
x = (y^7)/7 -4 . . . . . . . use the definition of f(x)
x +4 = (y^7)/7 . . . . . . add 4
7(x +4) = y^7 . . . . . . multiply by 7
(7(x +4))^(1/7) = y . . take the 7th root
The inverse function is the one shown in the attachment.

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
