Answer:

3. y = 2m + 40  ||    4. $78

Step-by-step explanation:

3.

Here y will be total cost, let months be m, $40 signup will be constant.

equation:  y = 2m + 40

4.

y = 2m + 40        [ Here given that the months is 19, m = 19 ]

y = 2(19) +40

y = 78

The total cost of being all-star library member for 19 months is $78

equation: y=2x+40
y=2•19+40 (plug in 19 months)
2•19=38
y=38+40=78
the total cost of being an all-star library member for 19 months is $78.
