Answer:
290 days
Explanation:
We know the starting cost is $500. Suppose the commercial is aired x times. That means the cost will be a total of 50x.
Adding that to 500, we get a total of 50x + 500.
The company's budget is only $15,000, so we set this equal to 50x + 500 to find x:
50x + 500 = 15,000
50x = 14,500
x = 290
The answer is 290 days.
