    Answer:

    The equation is x= (7.74 /9) 6  

    Step-by-step explanation:

    Hi, to answer this question we have to analyze the information given:

    If 9 pencils cost $7.74, we have to divide the total cost ($7.74) by the number of pencils (9) to obtain the price of 1 pencil.

    Now that we have the price of 1 pencil, to obtain the cost of 6 of them we simply multiply the result by six.

    Mathematically speaking:

    x= (7.74 /9) 6  

    Where:

    x = Cost of 6 pencils in $

    Solving:

    x = 0.86 x 6 = $5.16

    Answer:

    Y=7.74/9×(6)

    Step-by-step explanation:

    Here,we have the price of 9 pencils which costs $7.74 and to get the price of each one, we decide the total price by the number of pencils bought.

    Therefore, $7.74/9(price of each pencil)

    And then the price of 6 pencils will be: X= $7.74/9×(6)

    Note that x is the price of each pencil.
