Answer:
Each CD was $15.30.
Step-by-step explanation:
97.20-5.40= 91.80 => 91.80/6= 15.30
Answer: 17.20
So 6 x 16 = 96 Then I added 1 dollar and 20 cents to get it to $97.20. so the answer would most likely be 17.20 for each CD.. Sorry for any mistakes! Hope it helped and have a wonderful day! :))
second one: -4x +6
third one: 4x - 16
fourth: 245x + 30
fifth: 81x - 21x
(last one) sixth: 1600x + 8x
( if this goes wrong then I did something else)
