Final answer:
a. The value of the comic book increases by $0.20 per year. b. The initial value of the comic book is $1.50.
Step-by-step explanation:
a. The value of the comic book is given by the equation 0.20y + 1.50, where y is the number of years since it was released. The coefficient 0.20 represents the rate at which the value increases per year. Therefore, the value of the comic book increases by $0.20 per year.
b. To find the initial value of the comic book, we can substitute y = 0 into the equation. The initial value is given by 0.20(0) + 1.50 = $1.50.
