1. There are 60 students going on a field trip to the chocolate factory. The students are from three different classes. Mrs. Hooper's class has 24 students and Mr. Gomez's class has 18 students. Which of the equalities correctly
describes the students and could be used to solve for how many students are from Mr. Anderson's class? (Let A =
the number of students in Mr. Anderson's class.)
A. A + 18 = 24
B. A + A + A = 60
C. 60 - 18 = A - 24
D. 24 + 18 + A = 60
