Sal and her three friends plan to bowl one or two games each. Each game costs $2.50 each. Identify the independent and dependent quantities in the solution.Find reasonable domain and range value.

A.number of games;total cost;4 to 8 games;$10 to $20

B.total cost; number of games; 4 to 8 games;$10 to $20

C.total cost; number of games; $10 to $20; 4 to 8 games

D.number of games; total cost; $10 to $20; 4 to 8 games

Verified Answer :

so the dependent is the number of games because it's not definite they dont know for sure. so the domain always involves money!!! always! the range wiyld be the numbers they migh play like 8-10 so 4 to 8 is the range value. so determining off of that the indepedent variable would be the total cost becuase it wont change so your answer is C hope this helped have a good day!!!

Answer:

The correct option is A.

Step-by-step explanation:

It is given that Sal and her three friends plan to bowl one or two games each. Each game costs $2.50 each.

Let x represents the number of games and y represents the total cost.

@@MATH_TOKEN_0@@

Here, x is independent variable and y is dependent variable. It means

Number of games = Independent quantity

Total cost = Dependent quantity

Number of persons = 4

Each person can bowl one or two games. So, reasonable domain of the function is 4 ≤ x ≤ 8.

Domain = 4 to 8 games

The value of y at x=4 is,

The value of y at x=8 is,

@@MATH_TOKEN_2@@

So, the reasonable range is $10 ≤ y ≤ $20.

Range = $10 to %20

Therefore the correct option is A.
