WRITE AN EQUATION

Students went on a field trip. Six buses were filled and 7 students traveled in cars. A total of 331 students went on the field trip. How many students were in each bus?

• 7x+6=331

• 13x=331

• 6x+7=331

• 331-7=6x

Mrs. Carter baked 100 muffins for a bake sale. The muffins were sold in packages of 2. There were 12 muffins left. Write an equation to find how many customers bought muffins at the bake sale.

• 12n + 2 = 100

• 2n -12 = 100

• 2n + 12 = 100

• 100n + 2 = 12
