    Worded problem.

    question number 1: The girls' and boys' basketball teams sponsored a car wash that made $109. There were twice as many girls as boys working, so a decision was made to give the girls twice as much of the money. How much money did each team make? Write a system of equations to solve this problem and round the answers to the nearest cent.

    question number 2 :
    In the relation shown below, (a) what is the domain and (b) what is the range?

    PLEASE HELP ASAP

    let x = amount of money each boy earned

    2x = amount of money each girl earned

    x + 2x = 109

    finish it


    question number 2 :
    In the relation shown below, (a) what is the domain and (b) what is the range?

    what's the definition of domain and range?
