Question

Mitch and his friends are planning a trip to the Tsunami Springs water park. The employee Mitch spoke to on the phone said the total cost for all 7 of them would be $154. This includes an entrance ticket and a $5 tube rental fee for each person. What is the cost of an entrance ticket

Answer 1

Entrance ticket is $17.

Step-by-step explanation:

Using a expression we can see the costs.

E - Entrance Ticket

T - Tube rental fee

7E + 7T = 154

Substitute T for the $5 that we know is the cost for tube rental.

7E + 7(5) = 154

7E + 35 = 154

-35 -35

7E = 119

/7 /7

E = $17
