60 = 1200. 10 = 200 : The cost per batch of 100 type 1 chips is $1900. The current sale price of each batch of 100 type 1 chips is $2000 + $1900 = $3900, or equivalently, $39 per chip. We do not produce type 1 chip in our optimal production mix, so the breakeven sale price must be greater than $39 per chip.
