Price of corn was 4%/ on Jan 2009 and 7%/ on Jan 2010. By what percentage did the corn price change from Jan 2009 to Jan 2010?
Something is missing
3%? doesn't look right, the corn wouldn't cost 4%, 4% of what?
To calculate the percentage change in the corn price from January 2009 to January 2010, we can use the following formula:
Percentage Change = ((Final Value - Initial Value) / Initial Value) * 100
In this case, the initial value is 4% and the final value is 7%. Let's substitute these values into the formula:
Percentage Change = ((7% - 4%) / 4%) * 100
Simplifying the equation:
Percentage Change = (3% / 4%) * 100
Percentage Change = 0.75 * 100
Percentage Change = 75%
Therefore, the corn price increased by 75% from January 2009 to January 2010.
