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,excluding sales tax.
What is the current price of each towel?
(A)$1
(B)$2
(C)$3
(D)$4
(E)$12
答案是(C)
想請問一下 題目是說增加$1還是$1.1阿? 有點看不太懂
感謝~
