Answer:
x ≤ 20
B is correct.
Explanation:
A water park charges $6 for admission and $1.50 for each ride ticket.
Let we take x number of rides.
Total charges for rides and admission fees
Total charges = 6 + 1.5n
We have only $36
So, Total charges should be less than 36
Equation:
6 + 1.5x ≤ 36
Now, we will solve for x
1.5x ≤ 30
x ≤ 20
So, We can take maximum 20 ride.
Now we make graph of solution. Please find attachment for graph.
