Please help I don’t understand. The value of a baseball player's rookie card began to increase once the player retired.
When he retired in 1996 his card was worth $7.86. The value has increased by $1.68 each year
since then. Express the relationship relating the value of the card y in dollars and the number of
years x the player has been in retirement with an equation. Is the relationship between x and y
proportional? What was the value of the card in 2006?
