A. 2
B. 3
C. 4
D. 5

Answer 1

A total of 4 buses will be needed to transport Mrs. Fields and Mr. Snow's combined classes of 76 students and the 2 teachers, since each bus can carry 22 riders and we round up when dealing with whole units required for transportation.

Step-by-step explanation:

To determine how many buses will be needed for the field trip with Mrs. Fields and Mr. Snow's classes, we must first calculate the total number of riders, including both students and teachers. With 38 students in each class, the total number of students is 38 multiplied by 2, which equals 76. Since there are two teachers, we add them to the student count, resulting in 78 people who need transportation.

Each bus holds 22 riders, so we divide the total number of riders by the number of riders a bus can hold. Doing the math, 78 divided by 22 equals 3.545. Since we cannot have a fraction of a bus, we must round up to the nearest whole number. Therefore, 4 buses will be needed to transport everyone.
