the 8th grade class planned a trip to kings dominoin and 120 student went. Ten students rode with their parents. The rest rode on two charter busses. How many students werer on each bus?

Step one: 120-10=110

Step two: 110/2=55

Answer: 55 students per bus

We can write this out with the following, if kids who went on the bus is x and kids who went with their parents is y.

x + y = 120

we know that y = 10, since 10 kids went with their parents.

plug this in to the original equation

x + 10 = 120

x = 110.

since there are two charter buses, divide 110 by 2.

There were 55 students on each charter bus.
