# Change of gas from 1990 to 2014 in Colorado

Have to gas prices changed since 1990?

Do you think the price of gas is too much? Here is the information I found:

1990: Gas costed $1.30 a gallon.

2014: Gas costed $3.57 a gallon.

The price of gas has gone up by $2.27. Now lets figure out how much that is in percentage.

First you need to subtract $3.57 by $1.30. Then you divide that by 3.57. Now, you times that number by 100. Put a percent at the end and that's the percent of change. Our answer is a 274.61% increase.

I think this is a huge increase!

These are some of the sources I got this information from:
