Answer:
76
Step-by-step explanation:
80 x 0.05 = 4
80 - 4 = 76
A) 1104/ 138 = 8
B) 1st = 30/2 = 15, 2nd = 15/2 = 7.5, 3rd = 7.5/2 = 3.75, 4th 3.75/2 = 1.875, 5th = 1.875/2 = 0.9375, 6th = 0.9375/2 = 0.46875, 7th = 0.46875/2 = 0.234375, 8th = 0.234375/2 = 0.117 = 0.12
Answer is B
14x + 70 + 20x + 8 = 180
34x + 78 = 180
34x = 102
x = 3
ABX = 14(3) + 70 = 112
CBX = 180 - 112 = 68
