Can you help find out what the percent increase is?

Question

Todd bought a pack of basketball cards that contained a rookie card of a player who later became famous. He paid %0.03 for the rookie card, and fifteen years later, the card was worth $1200. Determine the percent increase of the card's value.

Answer 1

First you calculate the actual monetary increase i.e. 1200-0.03 = 1199.97

Then make a ratio of the increased amount divided by the original amount i.e. 1199.97/0.03. To determine the percent increase simply multiply by 100. The answer is 3,999,900%.
