The distance between (3, 1) and (6, 5) is 5.
D=√(x₂-x₁)²+(y₂-y₁)²
D=√(6-3)²+(5-1)²
D=√3²+4²
D=√9+16
D=√25
D=5
<span>Cost of material =$84
Selling Price of each bracelet=$3.50
Let b be the number of bracelets to be sold.
Let P be the profit.
To get a profit Selling price should be greater than cost price.
Profit = Selling Price - Cost price
$3.50 * b would give the total selling price.
Therefore,
P=3.50b - 84</span>
The answer is A! it equals 360°!
