In the figure above C is the midpoint of BD and AC = DE. What is the value of n ?
A) 30
B) 45
C) 60
D) Cannot be determined from the information given14 .Allie is a caterer who is building 4 sandwich platters. Each sandwich platter contains
turkey slices that weigh 2 ounces each and bread slices that weigh 1 ounce each. In each
platter, she has a total of 100 slices of turkey and bread that weigh a total of 160 ounces.
Solving which of the following system of equations yields the number of turkey slices, t,
and the number of bread slices, b, that are in the 4 sandwich platters?
A) t + b = 100
2 t + b = 160
B) t + b = 160
2 t + b = 100
C) t + b = 400
2 t + b = 160
D) t + b = 400
2 t + b = 640
