Expressions and Equations

The 5th grade students are going on a field trip to the museum. The students will need four buses, each containing 18 students and two buses, each containing 22 students to get to the museum. What equation shows how to find s, the total number of 5th grade students that are going to the museum?

• s = (4 + 18) + (2 + 22)

• s = (4 x 18) x (2 x 22)

• s = (4 + 18) x (2 + 22)

• s = (4 x 18) + (2 x 22)
