The value of a baseball card in dollars has been found to be 0.15y + 0.35, where y is the number of years since it was released. By how much is the baseball card's value increasing per year?

Question

A.
$0.15

B.
$0.35

C.
15%

D.
35%

Answer 1

The value of the baseball card, given by the formula \( V = 0.15y + 0.35 \), indicates how the value changes over the years.

The coefficient of \( y \) in this equation represents the annual increase in value. Here, the coefficient is \( 0.15 \).

Therefore, the baseball card's value is increasing by $0.15 per year.

The correct answer is:

A. $0.15
