Answer:
54 students per bus.
Step-by-step explanation:
To find how many students traveled in each bus, we must first know how many travelled in all the buses.
There are 331 students in all, and 7 did not travel in a bus.
331 - 7 =<u> 324 </u>
If each bus had the same amount of passengers, then we can use an average to find out how many were in each bus. s = students and b = busses
There were 54 students per bus.

For this case we must construct a system of two equations with two variables. Let "h" be the number of hardcover version books, and let "p" be the number of paperback version books. If the hardcover version of a book weighs 7 ounces and the paperback version weighs 5 ounces, to reach a total of 249 ounces we have:
(1)
On the other hand, if there are Forty-five copies of the book then:
(2)
If from (2) we clear the number of books paperback version we have:
As each paperback version book weighs 5 ounces, to obtain the total weight of the paperback version books, represented by "x" in the table shown, we multiply
So,
