The answer is D. 64. Have a nice day!
3m + 2n= p solve for n
subtract 3m on both sides
2n = p - 3m
divide both sides by 2
n = p/2 - 3m/2
-----------------------
xy - 5 = k solve for x
add 5 on both sides
xy = k + 5
divide both sides by y
x = k/y - 5/y

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.
