  1. Charles' wages = 9c + 32
    Stacey's wages = 9s

    Total of their wages = 9c + 32 + 9s <----- choice a)
    = 9(c+s) + 32 <---- choice d)

    So you have 2 correct choices.
    Often incorrect choices can be traced to making some error
    in order of operation, misunderstanding the problem, ....
    I wonder where the 28 in the last choice could possible be
    arrived at.
