Rob makes metal sculptures to sellat craft shows. his initial cost fordesigning the sculptures and buyingthe welding equipment is $200. ltcosts him $10 for materials to makeeach sculpture. he can sell them for$50 apiece. how many must he sellto break even?

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.

127 millimeters is the answer
