Answer: cost of drop tower = $4
Cost of log ride = $2
Cost of dragster= $6
Step-by-step explanation:
Let x = Cost of drop tower.
Then , cost of log ride = [tex]\dfrac{1}{2}x[/tex]
Cost of dragster = [tex]3\times\dfrac12 x=\dfrac32 x[/tex]
Total cost = [tex]x+\dfrac12x +\dfrac32 x=\dfrac{2x+x+3x}{2}=\dfrac{6x}{2}=3x[/tex]
Given: Total cost of rides = $12
So, 3x = 12
⇒ x= 4 [divide both sides by 3]
So, cost of drop tower = $4
Cost of log ride = [tex]\dfrac12 \times 4=\$2[/tex]
Cost of dragster = [tex]\dfrac32 (4)=\$6[/tex]
