A store currently charges the same price for each towel that it sells.

If the current price of each towel were to be increased by $1, 10 fewer of the towels could be bought for $120, exluding sales tax.

What is the current price of each towel?(C)

A.$1 B.$2 C.$3 D.$4 E.$12

题目中文的意思是指,如果现在每条毛巾价格上涨1元,那么现在可以买120元的毛巾数量比原先120元可买的毛巾数量少10条

你可以设原先的毛巾每条X元, 现在是X+1

120/X-10=120/(X+1)

得到X=3
