ok. their are 14 members. 6 members payed their dues in week 1. so, subtract 6 from 14. <em>14 - 6 = 8.</em> Now, the due is $12.55. 8 members payed their dues in week 2, so multiply 8 by 12.55. <em>8 x 12.55 = 100.50 </em>the answer SHOULD be $100.50 i would think, but there is not an option for that. so, i would pick option 4, because that is .10 off from 100.50. Good luck!!
