    Archie: x+20

    Betty: 2x-5

    Step-by-step explanation:

    We are given that The number of cupcakes that Archie sold can be given as 20 more than a number, x.

    So, 20 more than x = x+20

    So, Archie sold cupcakes = x+20

    We are also given that Betty sold five fewer cupcakes than twice a number, x.

    So, twice a number, x = 2x

    Five fewer cupcakes than twice a number, x. = 2x-5

    So, Betty sold cupcakes = 2x-5

    Hence an algebraic expression that can be used to represent the amount of cupcakes that each senior sold

    Archie: x+20

    Betty: 2x-5
