    Step-by-step explanation:

    The printer charges a $27 set-up fee, plus $0.75 for each poster. The set up fee is constant.

    The cost y in dollars to print x posters is given by the linear equation

    y=0.75x+27.

    a) To find the cost, y in dollars to print 50 posters, we will substitute 50 for x in the given linear equation. It becomes

    y=0.75x+27

    y = 0.75 * 50 + 27

    y = 37.5 + 27 = $64.5

    b) To find the cost, y in dollars to print 100 posters, we will substitute 100 for x in the given linear equation. It becomes

    y=0.75x+27

    y = 0.75 * 100 + 27

    y = 75+27 = $102
