She paid .2 per magazine, so .2*number of magazines = 10. So the number of magazines she bought was 10/.2, or 50. Since that was only half of them, there were 100 total.
a d=.2m b. You make a function table. Just plug the points into d=.2m

Cynthia bought 50 magazines for $10, meaning there were 100 in total. The payment function is expressed as d = 0.20m. A function table was created showing four pairs of magazines and their costs.
