DAILY DOUBLE WITH A TWIST
You may wager an amount from 0-3000 points. The amount you wager can then be placed against another team. If you answer correctly you take the points from the team you placed the wager against. If you answer incorrectly you will give that many points to the team you wagered against.
Compound interest will also add the interest you receive onto the additional interest that you earned previously. Thus a shorter compounding period allows for a higher interest earned (weekly vs yearly) and a longer compounding period causes lower interest earned (monthly vs weekly).

The solution below contains two errors. Identify where the errors occur, explain why they are incorrect, and show the correct solution.
4(x + 2) - 3(x - 2) = 5
4x + 8 - 3x - 6 = 5
x + 2 = 5
x = 5 + 2
x = 7
Error in the second line (Did not distribute the -3 properly as the -2 should have become +6 not -6)
Error in the 4th line (When moving the + 2 to the right side did not use inverse operations, needed to subtract on the right side instead)
Correct answer: x = - 9
