12. The average of x numbers is 15.
If two of the numbers are each increased by y, the new average will be increased by how much?
:
We can write the original average as (for understanding purposes):
= 15 average
:
We add y to two of the numbers and we have
= the new average
:
The difference between the two averages
- 15
we can write it as two fractions
+ - 15
Cancel x, 15 is eliminated
15 + - 15 = is the increase in average
