Some plastic chairs are designed to be stackable. After the first chair in the stack, each additional chair adds the same amount to the overall height of the stack. The table below shows the total height of the stack when there are 1, 2, 3, and 4 chairs in the stack. Which function models the height of a stack of n chairs?
Number of chairs, n 1 2 3 4
Height of stack (inches) 28 31 34 37(1 point)
