Question

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?
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 look at the formula provided: \(0.15y + 0.35\).

In this formula:

• \(0.15y\) represents the value increase per year based on the number of years since the card was released.
• The term \(0.35\) is a constant that does not change over time and represents the initial value of the card when \(y = 0\).

Since the coefficient of \(y\) is \(0.15\), the baseball card's value is increasing by \(0.15\) dollars per year.

Thus, the correct answer is:

A. $0.15
