A diameter is a line segment that has end points on a circle and passes through the centre of the circle.
To make an expression for any amount of passengers, you need to use x for each passenger. Fill in x with the amount of passengers. Your equation is:
75 + 6x. Now using this expression, we can find the answer to all of the amounts of passengers.
75 + 6(25) = 225; 75 + 6(26) = 231; and so on. Hope that I helped! Good luck!
