Hope this helped! :))
From the information given,
3 pounds = $18
Therefore, 1 pound = 18/3 = $6 (this can be treated as a constant of proportionality) such that,
Cost,C = 6*Weight, W (pounds)
Equation;
C = 6W, where C = Cost in $, and W = Weight in pounds.
Answer:
The required equation is
.
Step-by-step explanation:
Consider the provided information.
The Initial value of poster = $ 18
After 1 year amount of increase = $ 20.70
With the rate of 15% = 0.15
Let future value is y and the number of years be x.

Now verify this by substituting x=1 in above equation.

Which is true.
Hence, the required equation is
.
