Norma-Jean [14]

Answer:

Sara should sell each bracelet at $8.50 to make a profit of $99.

Step-by-step explanation:

We are given the following:

Total cost = $28.50

Total bracelets to be made = 15

Total profit to be made = $99

Let $x$ be the price at which Sara sells each bracelet to make a profit of $99.

$\text{Total sales done = Number of bracelets sold }\times \text{ Sales price of each bracelet}\\$

$\Rightarrow 15 \times x ...... (1)$

Also,

$\text{Total sales price = Total Cost}+ \text{Total Profit} \\$

$\Rightarrow \$28.50 + \$99 ....... (2)$

Equating (1) and (2):

$\Rightarrow 28.50 + 99 = 15x\\\Rightarrow x = \dfrac{127.5}{15}\\\Rightarrow x = $8.50$

Sara should sell each bracelet at $8.50 to make a profit of $99.
