Imagine a start$-$up company producing a new prodct: The sale price of the product is $35000$ TL$/$kg$.$ The design capacity is $5000$ ton$/$year$.$ The fixed capital investment is $1010$ TL$.$ Straight line depreciation may be applied for the project life of $10$ years to zero salvage value. All other fixed charges are $2\backslash$times $109$ TL$/$year$.$ Variable cost except for the raw material cost is $15000$ TL$/$kg$.$

a$-$ What must be the price of raw material $($TL$/$kg$)$ at a full capacity to get $25\%$ return on investment? Assume the tax ratio is $40\%.(20)$

b$-$ Use the raw material price you calculated in part $($a$)$ to determine the capacity at the breakeven point. $(20)$
