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

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.

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,

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

Range = $10 to %20

Therefore the correct option is A.
