I somehow didn't get the question. Some explanation would be nice. Thanks!
The easiest -- and quickest -- approach is to plug in the answers, which represent the price per towel.
Answer choice C: price per towel = $3
For $120, 120/3 = 40 towels could be bought.
Price increased by $1 = 3+1 = $4 per towel.
For $120, 120/4 = 30 towels could be bought.
40-30 = 10 fewer towels. Success!
