Sum = adding correct.
That means we need to add 7+5 =12
and add the /8 to it
12/8
But thats improper so we need to simplify.
1 4/8
But theres still some simplifying.
4/8=1/2
That means your answer is 1 1/2
Hope this helped :)

Answer:
50%, 68.26%, 95.54%
Step-by-step explanation:
Let X be the day care costs
X is N(10000, 2000)
Since normal distribution is symmetrical about the mean we get
above 10000, exactly 50% of day care cost would be .
Between 8000 and 12000,
=
Between 6000 and 14000
%
