Answer:
Domain of the function is the set of whole numbers.
Step-by-step explanation:
The given function is
![c=45+3.75m](https://tex.z-dn.net/?f=c%3D45%2B3.75m)
where, c represents the cost of the yearly subscription and m is the number of magazines.
We need to find the domain of the function.
Domain is the set of inputs. In other words domain of the function is the set of m values.
Number of magazines always a whole number (0,1,2,....) because the number of magazines can not be a decimal or negative value.
Therefore, the domain of the function is the set of whole numbers.
Answer:
The peak fare price is $2,2
Step-by-step explanation:
Considering
Person 1
5x + 4y= 17,40
Person 2
2x + 3y= 9,20
Isolating the x
2x= 9,20-3y
x=(9,20-3y)/2=4,6 -1,5y
x=4,6 -1,5y
Replacing in the other equation
5 (4,6 -1,5y) + 4y=17,40
23-7,5y+4y=17,40
23-17,40=7,5y-4y
5,6=3,5y
y=1,60 (this is the off peak fare)
x= 4,60-1,5y
x= 4,60-1,5*1,60
x=2,2 (this is the peak fare)
