Ineed a second opinion. is my answer correct? see pic below. complete the problem using the percentage table. profits as percentage of sales which industry had the greatest percentage increase in profits as a percentage of sales between 1970 and 1974? petroleum what was the percentage increase (to the nearest tenth)? 26.8%

The increase from 1970 to 1974 is by far the largest in the Chemicals industry.

... (8.2/5.0 - 1)×100% = 64%

You're first one is correct, with the increase of Petroleum being the most at 3.4%

However, the second one is incorrect, because you are finding the percentage increase, or 12.7 - 9.3 = 3.4%

So the second one is 3.4

hope this helps
