<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>
Step-by-step explanation:
y = 400 × 0.75
y = 300
300 milligrams = 0.75 hours
x = 3 hours
3(300) = 0.75x
900 = 0.75x
x = 1200
It would be a variable because it doesn't tell us how much he made. So put a random letter, I would use X.
Sinx = 5/14
x = 20.9
x = 21 degrees
answer
