A + b + c = 168
b = 1/3c
a = b + c....a = 1/3c + c = 4/3c
now we sub
4/3c + 1/3c + c = 168
8/3c = 168
c = 168 * 3/8
c = 504/8
c = 63 <=== Carlos collected 63 lbs
a = 4/3c
a = 4/3(63)
a = 252/3
a = 84 <== Amy collected 84 lbs
b = 1/3c
b = 1/3(63)
b = 63/3 <== Bruce collected 21 lbs
b = 21

Answer:
A is true and B is false.
Step-by-step explanation:
x + 6.2 ≥ 10.9
Replace x for 4.7...
4.7 + 6.2 ≥ 10.9
10. ≥ 10.9 ( So this is true!)
x - 6.2 ≤ - 5
Replace x for 4.7...
4.7 - 6.2 ≤ -5
-1.2 is not ≤ -5 (So this is false!)
