The average of 9z numbers is 12z. If 4z-2 is subtracted from each, then the new average is?
Question
Solution 1
The problem states that the average of 9z numbers is 12z. This means that the total sum of all the numbers is 9z * 12z = 108z^2.
Then, it says that 4z-2 is subtracted from each number. Since there are 9z numbers, the total amount subtracted from the sum is (4z-2) * 9z = 36z^2 - 18z.
