Answer: C. 40.4%
Step-by-step explanation:
To find the rate of change in production, we can use the following formula:
Rate of change = (New value - Old value) / Old value * 100
Where,
Old value = Production of last month = 900
New value = Production of this month = 1264
Substituting the values in the formula,
Rate of change = (1264 - 900) / 900 * 100= 364 / 900 * 100= 0.404 * 100= 40.4%
Therefore, the rate of change in production is 40.4%, which is an option (c). I hope that this answer has helped you!
