Question

Help me PLEASE This is confusing and im getting frustrated. Ill brainliest the best answer with a good explanation so I can have a better understanding of the equation.

Answer 1

Answer:

Nina would have total expenses and sales $156 after selling 4 necklaces.

Step-by-step explanation:

Let x represent the amount of necklaces made and sold.

The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing x necklaces can be represented as:

$\displaystyle 140 + 4x$

Each necklace sells for $39. Hence, the total profit after selling x necklaces can be represented as:

$\displaystyle 39x$

To break even, the total cost and profit must be equivalent. Hence:

$\displaystyle 140 + 4x = 39x$

Solve for x:

$\displaystyle \begin{aligned} 140 + 4x & = 39x \\ \\ 140 & = 35x \\ \\ x & = 4 \end{aligned}$

Hence, the break even, Nina would need to sell four necklaces.

And the total expenses/profit would be:

$\displaystyle \ 39(4) = \ 156$

In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.

Answer 2

Answer:

• The total expenses is $156 is the total necklaces sold is 4.

Step-by-step explanation:

We know that:

• x = Necklaces created and sold
• 140 + 4(x) = Total cost
• 39x = Profit = Total cost
• Profit = Total cost

Work:

• 140 + 4x = 39x
• => 140 = 39x - 4x
• => 140 = 35x
• => x = 140/35
• => x = 4

Now, let's substitute the value of x into any equation to find the total expenses and sales.

• 140 + 4x
• => 140 + 4(4)
• => 156

Hence, the total expenses is $156 is the total necklaces sold is 4.

Hoped this helped.
