Question

Fun Lanes Bowling charges a fee of $4 to use their shoes and $6 for each game played. Salim wants to figure out how much it will cost him to bowl.

Part 1: Write an equation representing this problem. Let x be the number of games bowled, and let y be the total cost.

Part 2: Is x the dependent variable or the independent variable? Using complete sentences, explain how you know.

Answer 1

Drea
Write down your statistics on a sheet with word problems.
you have
$4 for shoe rental
$6 for a game
You don't know how many games will be played so this is X.
You will not know how much for the total excursion so this is y.

Familiarize with a scenario.
Let's say you only played one game.
what would the equation be?
4+6 = 10, right?
OK, now what if you wanted to see if you had enough money to play 4 games,
how would you set that up?
4+6(4)= ? right?
so the original equation
would be 4+6x=y
Does that make sense?

How do you define independant and dependant?
Independant can be controlled and dependant cannot.
Can you control the number of games you play? Yes. So the x is independant.
