Ms. Chapman wants to take her scout troop to Neon Nights roller rink. The employee she spoke to ahead of time said the total cost for all \( 9 \) people in the group would be \( \$ 81 \) . This includes an entrance ticket and a \( \$ 3 \) skate rental fee for each person. Which equation can you use to find \( t \) , the cost of each entrance ticket?
\( 3 ( t + 9 ) = 81 \) \(3 t + 9 = 81\)
\( 9 t + 3 = 81 \) \(9 ( t ) = 81\)
How much does each entrance ticket cost?
