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?

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.

Step one: 120-10=110

Step two: 110/2=55

Answer: 55 students per bus
