Amy earns 2% interest for here 5 000 dollars deposit. Meaning she will be receiving 2% every years. Now, in 4 years. How much will she receive?
Solutions:
1st year = 5 000 * .02 = 100
=> 5000 + 100 = 5100
2nd year = 5100 * .02 = 102
=> 5100 + 102 = 5202
3rd year = 5202 * 0.02 = 104.04
=> 5202 + 104.04 = 5306.04
4th year = 5306.04 * .02 = 106.1208
=> 5306.04 + 106.1208 = 5412.1608 or approximately 5412.16
Im pretty sure Kristen is right because Kristen didn't win free games. 4M is for each game Mateo has played while 4K is for each game Kristen played in a sense of paying. The 5 is standalone for the free since it's a constant.
