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 times (ad bud)
180,000 = 60(ad bud)
Advertising budget = $3000 this is how much the owner is spending on advertising budget.
