Anna and Liam time travel the country selling handmade leather bracelets at the state fair. Before traveling to Newtown, they buy a bunch of leather strips from a local shop for $136. If they sell their bracelets for eight dollars apiece, write an equation that can be used to describe their profit P in relation to the number of bracelets B that they sell at one state fair?

P = $8B - $136

Step-by-step explanation:

Mathematically the profit can be calculated by subtracting the cost price from the selling price

Here, the cost price is $136

Now, their selling price is obtained by multiplying the number of pieces sold by the selling price of each piece

The number of pieces of bracelets is B and they sold at $8 per piece, the selling price of all is thus $8 * B = $8B

The profit P = selling price - Cost price = $8B - $136
