Arithmetic Sequences Problem

[From: ] [author: ] [Date: 11-05-02] [Hit: ]
8 = 1.She made 18 dishes (like you said).......
A cook started with 26 ounces of special sauce. She used 1.4
ounces of the sauce in each of a number of dishes and had 2.2
ounces left over. How many dishes did she make with the
sauce?

I know the answer is 18 dishes but how do you get that without using the long way and just using the formula

-
26 = 2.2 + (n - 1)(1.4)
23.8 = 1.4 (n - 1)
17 = n - 1
n = 18

She made 18 dishes (like you said).
