The amount of carbon dioxide $(\text{CO}_2)$ in the atmosphere increases rapidly as we continue to rely on fossil fuels.
The relationship between the elapsed time, $t$, in decades, since $\text{CO}_2$ levels were first measured, and the total amount of $\text{CO}_2$ in the atmosphere, $A_{\text{decade}}(t)$, in parts per million, is modeled by the following function:
###$A_{\text{decade}}(t)=315\cdot (1.06)\^{\Large t}$
**Complete the following sentence about the *yearly* rate of change in the amount of $\text{CO}_2$ in the atmosphere.**
*Round your answer to four decimal places.*
Every ***year***, the amount of $\text{CO}_2$ in the atmosphere increases by a factor of [[☃ numeric-input 1]].
