total number of pencils Sarah purchased: n = 12p
n = total number of pencils

independent variable: p
dependent variable: n
╔═══╦══════════╦════╗
║ p ║ n = 12p ║ n ║
╠═══╬══════════╬════╣
║ 3 ║ n = 12*3 ║ 36 ║
╠═══╬══════════╬════╣
║ 4 ║ n = 12*4 ║ 48 ║

║ 5 ║ n = 12*5 ║ 60 ║

╠═══╬══════════╬════╣
║ 7 ║ n = 12*7 ║ 84 ║
