Answer
a) In a typical June, Chicago has 3.7 inches of rain.
b) Chicago has 1.8 inches of rain in January and in February.
Work Step by Step
(a) The table shows $f(6)=3.7$, so $t=6$. In a typical June, Chicago has 3.7 inches of rain.
(b) First evaluate $f(2)=1.8$. Solving $f(t)=1.8$ gives $t=1$ or $t=2$. Chicago has 1.8 inches of rain in January and in February.
