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

To determine how much the baseball card's value is increasing per year, we can analyze the equation provided for its value:

\[ \text{Value} = 0.15y + 0.35 \]

In this equation, \( y \) represents the number of years since the card was released. The coefficient of \( y \) (which is 0.15) indicates the increase in the value of the card for each additional year.

Therefore, the baseball card's value is increasing by:

A. $0.15 per year.
