Suppose in the early 1900s the levels of CO2 in the atmosphere was only 64% of the levels of CO2 today. What percentage more is the level of CO2 today compared to the levels of CO2 in the early 1900s?
x in 1900
y in 2015
x = .64 y
so
y = 1.56 x
so y now is 156 percent of x
which is an increase of 56 percent
How did you get y=1.56x?
100/64= 1.5625
subtract by 1
move decimal
To find the percentage increase in the level of CO2 today compared to the levels in the early 1900s, we can follow these steps:
Step 1: Calculate the difference between the CO2 levels today and the levels in the early 1900s.
Difference = CO2 levels today - CO2 levels in the early 1900s.
Step 2: Calculate the percentage increase.
Percentage Increase = (Difference / CO2 levels in the early 1900s) x 100.
Let's apply these steps to solve your problem:
Step 1: Calculate the difference between the CO2 levels today and the levels in the early 1900s.
64% of the CO2 levels today = 0.64 * CO2 levels today.
Difference = CO2 levels today - 0.64 * CO2 levels today.
Difference = 1 * CO2 levels today - 0.64 * CO2 levels today.
Difference = 0.36 * CO2 levels today.
Step 2: Calculate the percentage increase.
Percentage Increase = (0.36 * CO2 levels today / CO2 levels in the early 1900s) x 100.
Since we don't know the actual values for CO2 levels today and in the early 1900s, we cannot compute the exact percentage increase.
However, if you provide the specific values for CO2 levels today and in the early 1900s, we can substitute those values into the equation to find the percentage increase.
