Answer:
13%
Step-by-step explanation:
Increase = (New Number - Old Number) / Old Number
(130 - 115) / 115
15/115 = 0.130434783.
0.130434783 * 100 (to get the percentage) = 13.0%
To find the mid segment, it is half of the sum of the bases
for number 13 it's 7+13=20 20/2=10
number 14 it's 12+9=21 21/2=10.5
number 15 it's 22+18=40 40/2=20
171 rounds to 200, and 727 rounds to 700. 700+200= 900.
The answer is 900.
