Question

a lightbulb manufacturer would like to increase production from 1.4 million to 3.9 million lightbulbs per year. find the percent increase of the production expectation. ( round your answer to one decimal place)​

Answer 1

The percentage increase of the production expectation to 1 decimal place is 178.6%

Explanation:

Here in this question, we are interested in finding the percentage increase in the production capacity of the hypothetical company;

We can make or have a formula for this to make our workings easier;

% increase = (new value - old value)/old value * 100%

From the question;

The old value is the former productive capacity which is 1.4 million

The new productive capacity is 3.9 million

Thus;

The percentage increase in the production capacity would be;

(3.9 million - 1.4 million)/1.4 million * 100%

= 2.5 million/1.4 million * 100% = 178.57%

But the question asks we should have our answer in one decimal place;

Thus; 178.57% becomes 178.6%
