I think the proportion of the numbers from 1-1000 that contains 3 is 261 out of 1000 number and it includes the numbers in 300 place. I hope you are satisfied with my answer and feel free to ask for more if you have clarifications and further questions.
Answer:
The answer is 9
Step-by-step explanation:
Solution: We have to choose two positions president and vice president from eight people. So, we need to use the Permutations formula in order to find the possible number of combinations.
The number of possible combinations is:
8P2 



Therefore the possible number of combination to select two positions from 8 people is 56
For this case, the first thing we must do is define variables.
We have then:
x: number of rides
y: total cost
We now write the equations for each park.
For The Thrill amusement park:
y = 5x + 40
For The Splash water park:
y = 3x + 60
Answer:
A system of equations that could be used to determine the solution where the cost per ride of the two amusement parks, and, is the same is:
y = 5x + 40
y = 3x + 60
