Answer:
Sara should sell each bracelet at <em>$8.50</em> 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
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}\\](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20sales%20done%20%3D%20Number%20of%20bracelets%20sold%20%7D%5Ctimes%20%5Ctext%7B%20Sales%20price%20of%20each%20bracelet%7D%5C%5C)
![\Rightarrow 15 \times x ...... (1)](https://tex.z-dn.net/?f=%5CRightarrow%2015%20%5Ctimes%20x%20%20%20%20......%20%281%29)
Also,
![\text{Total sales price = Total Cost}+ \text{Total Profit} \\](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20sales%20price%20%3D%20Total%20Cost%7D%2B%20%5Ctext%7BTotal%20Profit%7D%20%5C%5C)
![\Rightarrow \$28.50 + \$99 ....... (2)](https://tex.z-dn.net/?f=%5CRightarrow%20%5C%2428.50%20%2B%20%5C%2499%20.......%20%282%29)
Equating (1) and (2):
![\Rightarrow 28.50 + 99 = 15x\\\Rightarrow x = \dfrac{127.5}{15}\\\Rightarrow x = $8.50](https://tex.z-dn.net/?f=%5CRightarrow%20%2028.50%20%2B%2099%20%3D%2015x%5C%5C%5CRightarrow%20x%20%3D%20%5Cdfrac%7B127.5%7D%7B15%7D%5C%5C%5CRightarrow%20x%20%3D%20%248.50)
Sara should <em>sell each bracelet at $8.50</em> to make a profit of $99.
