<h2>
∴ The value of min(10,w) = 10</h2>
Step-by-step explanation:
Given
- w = max (20,z) for some integer z
2. and w = max (10,w)
From the first equation we get that w= 20
and it also satisfies the second equation.
∴ The value of min(10,w) = min(10,20) ∵w=20
= 10
Answer:
16 rides
Step-by-step explanation:
Option 1 . Admission fee = $10
Each ride = $0.50
Option 2 . Admission fee = $6
Each ride = $0.75
Let no. of rides be x
So, cost of ride according to option 1 = 0.50x
So, total cost after having x rides according to option 1 :
= 10+0.50x ---1
Cost of ride according to option 2 = 0.75x
So, total cost after having x rides according to option 2 :
= 6+0.75x --2
Now to find the beak even point i.e. having the same cost
Equate 1 and 2





Thus for 16 rides , the two options have the same cost .
Hence the break even point is 16 rides
