Q. 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.

Calculate Total Cost per Person: First, we need to determine the total cost per person, including the skate rental fee. We know that the total cost for $9$ people is $\$81$ . To find the cost per person, we divide the total cost by the number of people. $\newline$ Calculation: $\$81 \div 9 = \$9$ per person (including skate rental fee).
Find Cost of Entrance Ticket: Next, we subtract the skate rental fee from the total cost per person to find the cost of the entrance ticket alone. We know that the skate rental fee is $\$3$ per person. $\newline$ Calculation: $\$9$ (total cost per person) - $\$3$ (skate rental fee) = $\$6$ per person for the entrance ticket.
