Tisha and her scout troop are heading to the Swing Time zip-line park. They plan to purchase the group package. With the package, the cost per person is $5 less than the normal cost for an individual. There are 12 scouts in Tisha's troop. Her troop leader called ahead and found that the total cost for the group will be $150. What is the normal cost for an individual?

Answer 1

Let x be the normal cost for an individual.
The cost for the group is 12 * (x - 5) = $150.
Thus, 12x - 60 = $150.
Thus, 12x = $150 + $60 = $210.
Thus, the normal cost for an individual is x = $210 / 12 = $<<210/12=17.5>>17.5. Answer: \boxed{17.5}.
