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?
Formula: rev=k(ad bud)
120,000=k(2000)
k=60
Equation: rev=60*(ad bud)
180,000=60(ad bud)
advertising budet = $3000
