Sara makes and sells bracelets. She bought material for $28.50 and used it all to make 15 bracelets. Sara used the equation to d

Norma-Jean [14]

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 $x$ 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 <em>sell each bracelet at $8.50</em> to make a profit of $99.

An English teacher needs to pick 1111 books to put on his reading list for the next school year. He has narrowed down his choice

forsale [732]

Answer:

There are 3,659,040 ways he can choose the books to put on the list.

Step-by-step explanation:

There are

12 novels

8 plays

12 nonfiction.

He wants to include

5 novels

4 plays

2 nonfiction

The order in which the novels, plays and nonfictions are chosen is not important. So we use the combinations formula to solve this problem.

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

How many ways can he choose the books to put on the list?

Novels:

5 from a set of 12. So

$C_{12,5} = \frac{12!}{5!7!} = 792$

Plays:

4 from a set of 8. So

$C_{8,4} = \frac{8!}{4!4!} = 70$

Nonfiction:

2 from a set of 12

$C_{12,2} = \frac{12!}{2!10!} = 66$

Total:

Multiplication of novels, plays and nonfiction.

$T = 792*70*66 = 3,659,040$

There are 3,659,040 ways he can choose the books to put on the list.
