David is trying to help Dad get more customers for his dad$$s new business. Dad was thinking of

buying ads on Facebook. David suggested sponsoring influencers on TikTok. $($Let$$s assume both

would be appropriate for the new business.$)$

The Facebook ads would cost $$500.$ There is a $20\%$ chance of those ads being successful and

leading to $$3,000$ of new business. If the ads are not as successful, Dad would only bring in an

additional $$300$ of new business.

It would cost $$200$ to sponsor an influencer. There is a $20\%$ chance of those ads being successful

and leading to $$4,000$ of new business. If the influencer bombs, Dad would only bring in an

additional $$100$ of new business.

David suggests that Dad use a decision tree. Draw and solve the decision tree for Dad. How

should Dad advertise his new business? How much should Dad expect to net as a result of this

advertising?
