Answer:
He will be able to carry the 6 boxes one go
Step-by-step explanation:
![1000g = 1kg \\720g = \frac{720 \times 1}{1000} \\ = 0.72kg](https://tex.z-dn.net/?f=1000g%20%3D%201kg%20%5C%5C720g%20%3D%20%5Cfrac%7B720%20%5Ctimes%201%7D%7B1000%7D%20%20%5C%5C%20%20%3D%200.72kg)
So each box is 0.72kg
then 6 boxes =
![0.72 \times 6 \\ = 4.32](https://tex.z-dn.net/?f=0.72%20%5Ctimes%206%20%5C%5C%20%20%3D%204.32)
and that's approximately 4 so in total the the 720g is actually 4kg and can be carried at once

Answer:
it is the first one
Step-by-step explanation:
Step-by-step explanation:
![\frac{5gb}{110} = \frac{2.3gb}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5gb%7D%7B110%7D%20%20%3D%20%20%5Cfrac%7B2.3gb%7D%7Bx%7D%20)
→ x = 2.3 ×110÷5 = 50.6 $ Aaron pay
→Brian = 1.1 × 110 ÷5=24.2$
Caleb = 110 - ( 24.2 + 50.6 ) = 110 -74.8 = 35.2$
