There are a hundred and fifty-five students going on the field trip there are five buses each row in the bus can hold 4 students how many rolls are needed in each bus

Answer 1

First, let's look at what information we were given:

1. We have a total of 155 students,
2. We have 5 buses, and...
3. There can be 4 students per (r) row.

With this we can write the following equation: 155 students = 5 buses × 4 students × r rows

Now, solve for the variable, r, to find the number of rows per bus needed.

You may need to round up to the nearest whole number for the answer to make sense.
