Subtract the 4
7x=42
Then divide by 7
X=6
Y-3=23(x-4) hope this helps
These are the points and just join them
K so the chance is 15/20 or 3/4 or 75%
Hope that helped :) if u dont get it i can try to explain :)
<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>
