To find the average cost of a pen, calculate the total cost of all pens and divide by the total number of pens. Total cost = (5 * $1.29) + (3 * $1.49) + (6 * $1.79) + (9 * $0.99) = $6.45 + $4.47 + $10.74 + $8.91 = $30.57. Total number of pens = 5 + 3 + 6 + 9 = 23. Average cost = $30.57 / 23 = $1.33.
