For 8 bracelets, total cost = Actual cost + shipping = $54
shipping = $6 (constant)
Actual cost = $54 - $6 = $48 (for 8 bracelet)
Cost of one bracelet = 48/8 = $6
Let y be total cost of bracelet, and x be total number of bracelet,
so, the equation of the cost of each bracelet would be
y = 6x + 6.

Im pretty sure it would be 54÷ b- 6 if your looking for only the cost of the braclets nothing else.

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (11, 4) → x₁ = 11, y₁ = 4

Point (5, 8) → x₂ = 5, y₂ = 8

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(5-11)^2+(8-4)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-6)^2+(4)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{36+16}$
[√Radical] Add: $\displaystyle d = \sqrt{52}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{13}$
