    Answer:

    (a)\ y = 26 + 0.44x

    (b)\ 114\ copies

    Step-by-step explanation:

    Given

    Base\ Charge = \$26

    Rate = 44c per copy

    Solving (a): Linear Equation

    The total charges (y) is: the base charge + the rate * number of copies (x).

    So, we have:

    y = 26 + 0.44 * x

    The 0.44 is 44 cents converted to dollars

    y = 26 + 0.44x

    Solving (b): Purchase if he budgets $76.16

    This implies that y = 76.16

    So, we have:

    y = 26 + 0.44x

    76.16 = 26 + 0.44x

    Collect like terms

    0.44x = 76.16 - 26

    0.44x = 50.16

    Solve for x

    x = \frac{50.16}{0.44}

    x = 114
