    Answer:

    Cost of each individual book = $10.5

    Step-by-step explanation:

    Given:

    Cost of 3 book set = $24.81

    Amount save = $6.69

    Find:

    Cost of each individual book

    Computation:

    Assume:

    Cost of each individual book = a

    Total cost = 3a

    So,

    Total cost = $24.81 + $6.69

    Total cost = $31.5

    So,

    3a = $31.5

    a = $10.5

    Cost of each individual book = $10.5
