Q15

1st get rid of the $1 from his mom

182 days / 7 = 26 sets
132.90 - 26 = 107.90 = 10790 cents

assume all coins are 20-cents
2 x 20 cents x 182 days = 7280 cents

10790 - 7280 = 3510

3510 / (50-20) = 117 50-cent coins

117 coins / 2 coins each day = 58.5 days. wrong answer :(

Do focus on your other papers now, you still have mother tongue and science ... no point worrying about what is over and done with ... you can still make it through :-)
