Answer:
Number of cells needed = 4
Step-by-step explanation:
The current output averages 200 units per cell, but the output will soon increase to 229 units per cell per day due to productivity improvements.
The current demand is 70000 units per year and it will triple in 2 years. Hence annual demand to be fulfilled is 70,000*3 = 210,000 units per year.
Assuming 243 workdays per year
Hence, Output per day * 243 = 210000
Output per day = 210000 / 243
Output per day = 864.20
As each cell will produce 229 units per day, number of cells needed will be 864.20 / 229
Hence, Number of cells needed = 4
