Question

multiple choice 5 points 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? 35% $0.15 $0.35 15% clear my selection previous

Explanation:

Step1: Analyze the linear equation

The value of the baseball card is given by the linear equation \( V(y) = 0.15y + 0.35 \), where \( y \) is the number of years since release. In a linear equation of the form \( y = mx + b \), \( m \) is the slope (rate of change) and \( b \) is the y - intercept (initial value).

Step2: Identify the rate of increase

For the equation \( V(y)=0.15y + 0.35 \), the coefficient of \( y \) (the slope) is \( 0.15 \). This slope represents the amount by which the value of the baseball card increases per year. Since the units of the value are in dollars, the rate of increase per year is \( \$0.15 \).

Answer:

\$0.15 (the option with text "\$0.15")
