Answer:
$0.95
Step-by-step explanation:
Given that weight of the function = x
Given that cost of the postage for mail having weight less than or equal to 1 oz = $0.44
then to find the equation can be written as
C(x)=0.44 where 0<x<=1
Similarly we can write equation for other parts
C(x)=0.61 where 1<x<=2
C(x)=0.78 where 2<x<=3
C(x)=0.95 where 3<x<=3.5
Now we can write them together as piecewise function as shown in below:
to graph that we just draw horizontal lines for each as none equation contains x on the right side .
3.48 oz is less that 3.5 so we will use $0.95.

of an hour was spent reviewing math problems and Adelina attended 
of the tutoring session.
We have to find the time Adelina spend at the tutoring session.
We know, 1 hour = 60 minutes.
Total time taken in tutoring session = 
minutes.
also, Adelina attended of the tutoring session that is of 40 minutes.
