On the day of the field trip, each teacher must call the parents of any student who has not returned a permission slip. All of M
r. Gomez’s students returned their permission slips, so he did not have to make any calls. Mrs. Hooper and Mr. Anderson had to call a total of eight parents. Mrs. Hooper needed to call two more students than Mr. Anderson which set of equations correctly describes the phone calls made h=mrs hooper
a=mr anderson
A. H+A=8 ; H=A+2
B. H+A=8 ; A=H+2
C. H+A=2 ; H=A+8
D. H+A=2 ; A=H+8
B is the correct answer. Since Mrs. Hooper and Mr. Anderson had to call a total of 8 parents, you know the first equation must be either A or B (H + A = 8).
Since you know that Mrs. Hooper had to call 2 more parents than Mr. Anderson, the equation will have to have H + 2 on one side; that's how you know the correct answer is B.
