Jean's dress was $10 less than Pauline's $30 dress, meaning it was 30-10= <<30-10=20>>20 dollars.
Ida's dress was $30 more than Jean's $20 dress, meaning it was 30+20=<<30+20=50>>50 dollars.
Patty's dress was $10 more than Ida's $50 dress, meaning it was 50+10=<<50+10=60>>60 dollars.
Therefore, all four women together spent 60+50+20+30=<<60+50+20+30=160>>160 dollars.
