What is the percentage decrement in the production of electric bulbs in October as compared to the production in July?
(Correct up to two decimal places.)

Accepted Answer

To find the percentage decrement in production from July to October, use the formula:

Percentage Decrement = ((Production in July - Production in October) / Production in July) × 100

Assuming from the bar graph:  
- Production in July = P_J = 550
- Production in October = P_O = 375

Calculate the difference: D = P_J - P_O = 550 - 375 = 175

Then calculate the percentage decrement:

Percentage Decrement = (D / P_J) × 100 = 31.818181 ~ 31.82%
