texaschic101 · Answer

The only way to get to shipwreck island is to take a boat, which is free for babies (2 and under), $17 for children (3 to 10 years old), $25 for seniors (62 and older), and $27 for everyone else. Delia paid $115 for 6 people in her family to go to the island for the day. Is it possible that great-grandma linda (91 years old) went to the trip? Explain your reasoning.

How do I solve this ? By trial and error ?
