The value of a baseball card in dollars has been found to be 0.15 + 0.35. where y is the number of years since it was released. By how much is the baseball card's value increasing per vear?
• A. $0.15
• B. $0.35
• C. 15%
• D. 35%
To find the rate at which the baseball card's value is increasing per year, we look at the coefficient of the variable "y" in the expression 0.15 + 0.35y.
As there is no "y" in the expression, it means that the value of the baseball card does not increase or decrease with each year. Thus, the value of the baseball card is not increasing per year.
Therefore, the answer is none of the given options.
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 vear?
• A. $0.15
• B. $0.35
• C. 15%
• D. 35%
To find the rate at which the baseball card's value is increasing per year, we look at the coefficient of the variable "y" in the expression 0.15y + 0.35.
The coefficient of "y" is 0.15, which means that for each year since it was released, the value of the baseball card increases by $0.15.
Therefore, the correct answer is A. $0.15.
To determine the increase in the baseball card's value per year, we need to find the coefficient of the variable 'y'.
In the given expression, 0.15 + 0.35y, the coefficient of 'y' is 0.35.
Therefore, the baseball card's value is increasing by $0.35 per year.
The correct answer is B. $0.35.
To find out how much the baseball card's value is increasing per year, we need to look at the coefficients of the variable "y" in the expression 0.15 + 0.35y.
In this case, the coefficient of "y" is 0.35. This coefficient tells us the rate of change of the baseball card's value with respect to time (in years). Therefore, the value of the baseball card is increasing by $0.35 per year.
So, the correct answer is option B. $0.35.
