743

9 weeks because 12x9= 108 and 108 is more than Malik need to repay but 108-12=96 less than needed so it is 9 weeks
First you want to find out how many marbles you start with so it'd be 8+7=15. You start with 15 marbles. If you randomly drew a blue marble, it'd be 8:15 and if you drew a yellow marble without replacing the blue one, it'd be 7:14 or 50-50 chance.
