Problem
In January 
the Mauna Loa Observatory recorded carbon dioxide (CO2) levels of 
ppm (parts per million). Over the years the average CO2 reading has increased by about 
ppm each year. What is the expected CO2 level in ppm in January 
? Round your answer to the nearest integer.
Solution 1
This is a time period of 
years, so we can expect the ppm to increase by 
.
