Question

Suppose there are n people on a bus. At the next stop, 4 more people get on the bus. No one getsoff the bus. Draw a bar diagram to model the number of people now on the bus. Use this model towrite an algebraic expression for the number of people now on the bus.Which bar diagram models the number of people now on the bus?
