Simon has a Wayne Gretzky rookie hockey card. He bought it in 2000 for $500 on e-Bay. He estimates that it will appreciate in value by 7% each year. The dealer told him the function V(t) 5 500(1 1 0.07)t can be used to estimate the card’s future value.

a) Explain how the numbers in the equation are related to the situation.
b) How much will the card be worth in 2020?
c) How long will it take for the card to double its value

Oh, I see. He uses "trial-and-error" 😆 In that case, just show that you guessed 9 -- didn't work (too low), 11 -- didn't work (too high), but 10.2 was just right!
