Answer:
B is more profitable when the production level is higher than 124,000 units, but lower than 192,500
Step-by-step explanation:
the difference between B and A per unit = $5
the difference in investment = $970,000 - $350,000 = $620,000
B is more profitable when total output is higher than $620,000 / $5 = 124,000 units
the difference between C and A = $8
the difference in investment = $2,510,000 - $970,000 = $1,540,000
C is more profitable when total output is higher than $1,540,000 / $8 = 192,500 units
