The northwood school math club is having a tamale sale. 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: 1580=x1600.
