You and your friends decide to fo play mini golf. "Volcano Adventures Mini Golf" asks you to pay $8 for a golf club and ball, then $12 per game. "Exotic Island Mini Golf" asks you to pay $16 for a golf club and ball, then $8 per game.

What is the solution to the system and what does it mean?

• (2, 32) at exactly 2 games of mini golf both places will cost $32.

• (1,20) at 20 days both mini golf places only have 1 person playing.

• (32, 2) at 32 games of mini golf both places will cost the same amount.
