Given:
Fixed cost: 200
Variable cost: 10 per sculpture
Sales price: 50 per scultpure
Break Even is when total sales is equal to total cost where profit is 0.
50x = 200 + 10x
50x - 10x = 200
40x = 200
x = 200/40
x = 5
He needs to make 5 sculptures to break even. For 6 sculpture and above, he will generate a profit.
