Write a function rule for the table
Answer:
[tex]c=16d +18[/tex]
Step-by-step explanation:
Let d is the number of days and c is the cost to rent
Lets find the difference in the cost of rent
50-34=16
66-50=16
82-66=16
Difference is a constant. so we use linear equation y=mx+b
m is the constant rate, x is our d and y is our 'c' cost
The equation becomes
[tex]c=16d +b[/tex]
To find out 'b' we use first row in the table
Plug in 1 for d and 34 for c
[tex]34=16(1) +b[/tex]
[tex]34=16+b[/tex], subtract 16 from both sides
[tex]b=18[/tex]
Function rule is
[tex]c=16d +18[/tex]
