To find the rate at which the value of the baseball card is increasing per year, we need to take the derivative of the given expression with respect to y.
Differentiating 0.15y + 0.35 with respect to y, we get:
d/dy (0.15y + 0.35) = 0.15
Therefore, the value of the baseball card is increasing by $0.15 per year.
Therefore, the answer is A. $0.15.
