Joel needs to hit some blank dvds and zip disks to back up a large amount of data that had been generated by an accounting firm. he buys 6 dvds and 3 zip disks for $96. he later realised these are not sufficient and so buys another 5 dvds and 4 zip disks for $116. how much did each dvd and each zip disk cost? (assume the same rate per item was charged for each visit.)
