If the value of the baseball card increases by 3% per year then we can say that each year the value of the card may be multiplied by 103% = 1.03, thus:
Value after n years = original price*(1.03)^n
Value after 15 years = 75*(1.03)^15
= $116.85

The height of Ernies shadow is 4 feet when his height is 6 feet.
<h3>
equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the length of his shadow. Given that the ratio of ernie's height to his shadow's height is 1.5 to 1. Hence:
- (1.5/2.5) * y = 6
- y = 10 feet
(1/2.5) * 10 = x
x = 4 feet
The height of Ernies shadow is 4 feet when his height is 6 feet.
