As part of a community service project at your high school, you are organizing a fund-raiser at the neighborhood movie theater. Money raised will benefit a summer camp for children with special needs. The admission charge is $10.00 per person, $5.50 of which is used to pay the movie theater’s rental fee. The remainder is donated to the summer camp fund.There are two variables involved in this problem. Which variable can best be designated as the dependent variable? As the independent variable?a.Independent variable - number of persons attending (or number of tickets sold);Dependent variable - the amount donatedb.Independent variable - the amount donated;Dependent variable - number of persons attending (or number of tickets sold)c.Independent variable - number of persons attending (or number of tickets sold);Dependent variable - the amount of the admission per persond.Independent variable - number of persons attending (or number of tickets sold);Dependent variable - the amount paid towards the movie theater’s rental fee.
The amount donated depends on how many people attend: each ticket brings in $10.00, and $5.50 goes to the theater, leaving $4.50 for the camp. So the number of people attending (or tickets sold) is the independent variable, and the amount donated is the dependent variable. This matches choice a.
