Final answer:
In the given scenario of selling $10 tickets for a fund-raiser, the independent variable is the 'Number of tickets sold' and the dependent variable is the 'Money raised' because the total funds collected depend on the number of tickets sold.
Step-by-step explanation:
In the scenario where a community-service organization is selling $10 tickets to a fund-raiser for the local children's hospital, the independent variable is the 'Number of tickets sold' and the dependent variable is the 'Money raised'. This is because the money raised through ticket sales depends on the quantity of tickets sold; for every ticket sold, $10 is added to the total money raised.
