Answer:
The card worth in 1997 is $9.98
The card worth in 1998 is $12.50
The card worth in 1999 is $15.02
The relationship is not proportional as the ratio of year to value would be constant .
Step-by-step explanation:
Consider the provided information.
The value of card is $7.46
The value of a baseball player's rookie card began to increase once the player retired in 1996. The value has increased by $2.52 each year since then.
Part (A) How much was the baseball card worth in 1997? In 1998? In 1999?
To find the card worth in 1997 simply add $2.52 and $7.46.
$7.46+$2.52=$9.98
Hence, the card worth in 1997 is $9.98
For 1998
To find the card worth in 1998 simply add $2.52 and $9.98.
$9.98+$2.52=$12.50
Hence, the card worth in 1998 is $12.50
For 1999
To find the card worth in 1999 simply add $2.52 and $12.50.
$12.50+$2.52=$15.02
Hence, the card worth in 1999 is $15.02
Part (b) Construct Arguments Why is there not a proportional relationship between the years since the player retired and the card value?
Proportional relationships are relationships where their proportions are equal for two variables.
Now find that whether the relation is proportional or not.
[tex]\frac{1996}{7.46} =\frac{1997}{9.98} \\267.56=200.100[/tex]
which is not true.
Hence, the relationship is not proportional as the ratio of year to value would be constant .
