According to the company's data the stadium has spent approximately $2.5 million on advertising over that period for 100 events. If the patrons to all of these events numbered 18.5 million, what is the ratio of patrons to advertising dollars?

The ratio of patrons to advertising dollars is 7.4:1

Explanation:

1. Let's review the information provided to answer this question correctly:

Amount spent on advertising by Memorial Stadium over the last 10 years = US$ 2.5 Million

Amount patrons numbered over the last 10 years = US$ 18.5 Million

2. What is the ratio of patrons to advertising dollars?

Ratio = Amount patrons numbered over the last 10 years/Amount spent on advertising by Memorial Stadium over the last 10 year

Ratio = 18.5 Million / 2.5 Million

Ratio = 18.5 / 2.5 = 7.4
