Carmen is renting buses for a school field trip. the number of buses needed depends on how many students are going on the trip. b = the number of buses needed s = the number of students going on the trip which of the variables is independent and which is dependent? s is the independent variable and b is the dependent variable b is the independent variable and s is the dependent variable

The Independent is the buses

Step-by-step explanation:

An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. ... The independent and dependent variables may be viewed in terms of cause and effect

Hope that helps feel free to ask me more questions:)
