Question

The value of a baseball card can be represented by the equation y=3x+39, where x represents the number of years that Robert has owned the card and y represents the total value, in dollars, of the card. What was the value of the card when Robert originally purchased it?

Answer 1

y=3x+39
x= years
y=value

Robert originally bought it 3 years ago, at the price of 39 dollars.

Answer 2

Answer:

Robert originally purchased the card for $39.

Step-by-step explanation:

Given: The value of a baseball card can be represented by the equation y=3x+39, where "x" represents the number of years that Robert has owned the card and "y" represents the total value, in dollars, of the card.

Here we asked to find the value of the card that Robert purchased.

Since  x presents the number years, to find the original cost, we have to plug in x = 0 in the given equation y = 3x + 39

When we plug in x = 0, we get

y = 3(0) + 39

y = 0 + 39

y = $39

Therefore, Robert originally purchased the card for $39.
