<PRE><B>Question 66657</B>
The revenue for a sandwich shop is directly proportional
to its advertising budget. When the owner spent $2000 a month on advertising, the
revenue was $120,000. If the revenue is now $180,000, how much is the owner
spending on advertising?
-----------------------
rev = k (ad bud)
120000=k(2000)
k=60
EQUATION: 
R = 60 b
If R=180000 find amount of advertising budget
180000=60(b)
b=$3000 (Amount of advertising budget.)
