The mean of 7 numbers is 15. When an 8th number is added the mean decreases to 12. What is the 8th number?

ale4655 [162]

Answer:

The 8th number is -9

Step-by-step explanation:

With an average, the sum of the seven numbers divided by 7 is 15.

In order to add an 8th number, we set up

$\frac{7*15+x}{8}=12\\105 + x = 96\\x = -9\\\\\frac{105-9}{8}=\frac{96}{8}=12$
