Answer:
Minimum 15 bracelets to be sold to meet the break even.
Explanation:
The cost price of bracelets is represented by C(x) =180+8x
The revenue earned (selling price) is represented by R(x) =20x
In these two functions x represents number of bracelets.
If P represents the profit then P = 20x-(180+8x)
P = 20x-180-8x = (12x-180)
For break even profit P = 0
12x-180 =0
12x = 180
x = 180÷12
x = 15
So minimum quantity of bracelets to be sold is 15 for the break even.
