The school has 1600 students, but the club members are not sure how many tamales to make.  One day during lunch, the club asked random students if they would buy a tamale.  They found that 15 out of 80 students surveyed said they would definitely buy a tamale.  How many tamales should the Math Club expect to sell?  Use the Fraction Busters Method to solve the proportion: <BR>\n" );
