Answer
Find out the percentage of students from the north side of the city in the program .
To prove
Formula

As given
A magnet school program was set up to bring in students from all over the city. With the first 112 students .
the magnet program had 50% from the south side of town, 12.5% from the north side l, and 37.5% from the east side.
12 .5 % is written in the decimal form.

= 0.125
North side student be = 0.125 × 112
= 14
As given
If 6 more student from the north side and 2 students from the west side side enrolled in the program .
than north side student becomes = 14 + 6
= 20
Total number of student becomes = 112 + 6 + 2
= 120
put in the above formula


= 16.66% (approx)
Therefore 16.66% (approx) students from the north side of the city in the program .
Answer:
Decrease of 28.6%.
Step-by-step explanation:
The multiplier for a increase of a% is 1 + a/100.
The multiplier for a decrease of b% is 1 - b/100.
Decrease of 15%
1 - 15/100 = 1 - 0.15 = 0.85
Decrease of 16%
1 - 16/100 = 1 - 0.16 = 0.84
Both:
0.85*0.84 = 0.714
Change:
The initial percentage is 100% = 1.
0.714 - 1 = -0.286
Negative, so a decrease
The answer is a decrease of 28.6%.
