A baseball card bought for $75 increases in value by 3% per year. what is the value of the card after 15 years

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
