Answer :
He must produce 129 necklaces, for a total cost of $1290 and a profit of $1290.
So according to the question ,
Each necklace costs him $7, but he makes $10 from selling them, thus his profit on each necklace is $3.
Profit can be determined by using formula :
Profit = Selling Price – Cost Price
Profit = 10 – 7
Profit = $3
Therefore, we need to determine how many necklaces he must produce and sell in order to recoup the initial investment.
387 divided by the profit per necklace yields 129.i.e
387/3 = 129.
He must create 129 necklaces.
The sum of the costs would equal the sum of the sales.
Sales of 10 dollars and 129 necklaces are sold, for a total of 1290 dollars (10*129) and 1290 dollars in expenses.
Therefore, he needs to produce 129 necklaces, for a total cost of $1290 and a profit of $1290.
