Alrighty

each necklace costs him 7 dollars but he gets 10 dollars from selling them

so his profit per necklace=10-7=3 per necklace

so we want to find how many necklaces he needs to make and sell to cover the initial investment

the cost is 387

divide it by the profit per necklace

387/3=129

needs to make 129 necklaces

the total expenses would be equal to the total sales

ok, the sales are 10 dollars and 129 necklaces so total sales is 1290 dollars and so then the expenses are 1290 dollars

129 necklaces

total expensese is $1290

total sales is $1290
