Answer
Explanation:
Step1: Analyze TV - ad situation
A $150 TV - ad causes 250 people to attend. Calculate the number of people per dollar for TV. Let $x$ be the number of people per dollar for TV. Then $x=\frac{250}{150}=\frac{5}{3}\approx1.67$ people per dollar.
Step2: Analyze newspaper - ad situation
A $350 newspaper ad causes 280 people to attend. Calculate the number of people per dollar for newspaper. Let $y$ be the number of people per dollar for newspaper. Then $y = \frac{280}{350}=0.8$ people per dollar.
Step3: Compare the two methods
Since $\frac{5}{3}>0.8$, the TV - ad is more cost - effective in terms of getting more people to attend per dollar.
Answer:
C. TV
