The value of a collectible coin can be represented by the equation y = 2 x + 15, where x represents its age in years and y represents its total value in dollars. What is the value of the coin after 19 years?

Question

$2
$23
$38
$53

Answer 1

To find the value of the collectible coin after 19 years, we can substitute \( x = 19 \) into the equation \( y = 2x + 15 \).

\[ y = 2(19) + 15 \]

Calculating the value:

\[ y = 38 + 15 \]

\[ y = 53 \]

Therefore, the value of the coin after 19 years is $53.
