Answer:
You can use the method of substitution.
Let the advance and same-day tickets be x and y respectively.
x + y = $70 ---> (1)
25x + 35y = $2050 ---> (2)
From Statement (1):
Let (1) × 25
25x + 25y = $1750
10y = $2050 - $1750
= $300
y = $300 ÷ 10
= $30 ---> (3)
From Statement (3):
Substitute (3) into (1)
x + $30 = $70
x = $70 - $30
= $40
Advance ticket: $40
Same-day ticket: $30

MMK so saying that a=3 and b=4 means substitute the letters, with the numbers. I'm not gonna do it for you but ill help you out a bit.
5. 2(3)+8=
8. 7(3) x 9(4)=
11. 3^2 + 1=
14. (3)(4)/3=
I think you can do the rest on ur own my friend. Hope this helped :)
Answer:
In statistics , the population is the set of all possible observations as per the researcher's objective .
For example if a researcher wants to find the average height of teenager of age group between 13 year and 15 years in Seattle, he will need the data of the population of height of teenager of age group between 13 year and 15 years in Seattle.
Here , A teacher needs to find out how many seventh graders will be going on a field trip.
Clearly as per her objective she need the data of all seventh graders .
So , the best describes the population that the teacher should survey would be : All seventh graders.
