Answer:
Nina would have total expenses and sales $156 after selling 4 necklaces.
Step-by-step explanation:
Let <em>x</em> 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 <em>x</em> necklaces can be represented as:

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

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

Solve for <em>x: </em>

<em />
<em />
Hence, the break even, Nina would need to sell four necklaces.
And the total expenses/profit would be:

In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.
Answer:
the answer is 48/100 im pretty sure .
Step-by-step explanation:
No solution.
2y-x=6 =y=1/2x+3
Since 1/2x does not equal 1/2x+3, this is a false statement and therefore has no solution
Answer:
The correct answer is last option
5/7
Step-by-step explanation:
It is given that, eight white balls and twenty black balls are in a bag
<u>To find the probability</u>
From the above data we get,
number of white balls = 8
Number of black balls = 20
total number of balls = 8 + 20 = 28
Probability of getting black ball = number of black ball/Total number of balls
= 20/28 = 5/7
The correct answer is last option
5/7
The formula for the area of the circle is:

All you have to do is plug in 8 for r :)
