pp3上一道数学题目,读不懂!

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

设现在的价格是x.

则 120/(x-1)-10=120/x

解的x=4
It is not only a test! It is Beyond GMAT!
