    The sum of the two remaining numbers, x and y = 60

    Question:

    The question isn't clear enough as some information have been omitted. Let's consider the following:

    Model with Math. The average of six numbers is 18. If the average of four numbers is 12. What must be the sum of the two remaining numbers, x and y?

    Write an equation to show how to find this sum.

    Step-by-step explanation:

    Mathematical models are applied to represent things in the real world in order to solve problems.

    The formula we would use to solve this problem is an example of a mathematical model.

    Types of mathematical model we can use include equations and graphs.

    Using equations:

    Average of six numbers = 18

    Average of four of the numbers = 12

    Total sum of the four numbers = 4*12 = 48

    the two unknown numbers are x and y

    Average of six numbers = (Sum of all 6 numbers) / 6

    = (Total sum of four numbers + x + y) / 6

    (48 + x + y) / 6 = 18

    The equation that shows how to find the sum:

    (1/6) (48 + x + y) = 18

    48 + x + y = 18*6

    48 + x + y = 108

    x + y = 108-48

    x+y = 60

    The sum of the two remaining numbers, x and y = 60
