Answer:
AD = 14
Step-by-step explanation:
BC = 6
BD = 8
CD = BD - BC
CD = 8 - 6
CD = 2
Since B is the midpoint of AC, therefore:
AC = 2*BC
AC = 2*6
AC = 12
Thus:
AD = AC + CD
AD = 12 + 2
AD = 14

Answer: a. 14% decrease or 86% of the whole
B. 137.5% increase
Step-by-step explanation:
A. Divide new price by old price and you get .86, change that to a percent by multiplying by 100. That equals 86%, the percent of change would be the difference of 100% to 86%, which is 14%
B. Use above explanation but don’t find the difference. 77/56= 1.375, 1.375*100=137.5
