Question

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 out of 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: .

Answer 1

15/80 = x/1600

multiply both sides of this equation by 1600 to get:

1600 * 15/80 = 1600 * x/1600

80 goes into 1600 20 times.

1600 goes into 1600 1 time.

equation becomes:

20 * 15 = x

solve for x to get x = 300.

300 students will most likely buy a tamale based on the survey
