    Answer:

    He brought 3 dozen cookies

    She ate \frac{2}{5} of the bag of Doritos

    She read 25 books

    Step-by-step explanation:

    ∵ Mike makes 4 dozen cookies

    ∵ He brings 75% of them for a party at his school

    – Multiply 75% by 4

    ∵ 75% = \frac{75}{100}=\frac{3}{4}

    ∴ He brought = \frac{3}{4} × 4

    ∴ He brought = 3

    He brought 3 dozen cookies

    ∵ Sam bought a bag of Doritos

    ∵ She ate only 40% of them

    ∵ 40% = \frac{40}{100}=\frac{2}{5}

    ∴ She ate = \frac{2}{5} × 1

    ∴ She ate = \frac{2}{5}

    She ate  \frac{2}{5} of the bag of Doritos

    ∵ Jamie took 50 books from the library

    ∵ She only read half of her whole stack

    – Multiply half by 50

    ∴ She read = \frac{1}{2} × 50

    ∴ She read = 25

    She read 25 books
