Question

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

The normal cost for an individual is $17.5

x = 17.5 or x = 17 1/2

Based on the given conditions, formulate: 12(x - 5) = 150 Apply Multiplicative Distribution Law: 12x - 60 = 150

Rearrange unknown terms to the left side of the equation: 12x = 150 + 60 Calculate the sum or difference: 12x = 210

Divide both sides of the equation by the coefficient of variable:

x = 210/12

get the result: x = 17.5 or x = 35/2 x = 17 1/2

Cross out the common factor:

Answer: x = 17.5 or x = 17 1/2
