Question
If the percent of corn produced that is used to make ethanol was $7 \%$ in 2000 , and about $40 \%$ in 2014 , what percent increase is that? What are some impacts of that trend?
Step 1
The formula for percent increase is: \[(\text{{New Value}} - \text{{Old Value}}) / \text{{Old Value}} \times 100\%\] Show more…
