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 />
<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:
56-7m
Step-by-step explanation:
l7m–56l m<8
so lets replace m with something smalller then 8, how about 7
so then it would be...
l 7 * 7 - 56 l=
l 49-56 l = l -7 l
but the absulute value of -7 is 7, so how does this help us? well lets see
56-49= 7 this proves that all we have to do is switch the order giving us the solution 56-7m
hope this helped :)
