    Answer:

    23pupils

    Step-by-step explanation:

    Given parameters:

    Number of 18th grade boys this year = 18

    Percentage decrease  = 28%

    Unknown:

    How many 8th grade teams were there last year  = ?

    Solution:

    Since this is a percentage decrease, ;

         Number of pupils this year  = Number of pupils last year – (28% x 18 )

                      18 + (28% x 18 ) = Number of pupils last year

             Number of pupils last year = 23pupils
