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 need to examine the formula given:

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

In this equation:

• \(y\) represents the number of years since the card was released.
• The term \(0.15y\) indicates that for every additional year, the value of the baseball card increases by \(0.15\) dollars.

Thus, the baseball card’s value is increasing by \(0.15\) dollars per year.

Therefore, the answer is:

A. $0.15
