100y+x=230
150y+x=320
Y being the price per kilogram of steel bar, x being the added delivery fee.
If you were to solve the equaltion it would go x=230-100y by changing the first equation around the replacing that for the x int he second group, so you would get 150y+230-100y=320 or 50y=90 So Y=9/5dollars per kilogram. Or $1.8per kilogram, the delivery fee being $50
In order to do this you add 15,682+18,940+16,114+12,468= 63,234
And that is larger than 50,000 so it is more.
63,324-50,000= 13,234

1. LI = 12
2. TV = 8.75, X = 9.75
3. No, it would be if AD = 15, DB = 12 and AE = 10, EC = 8.
4. No, CE needs to = 1/2 of AE, not 1/3.
5. Yes, DB and EC are each 1/3 of AB and AC.
6. X = 15
7. X = 9
8. X = 8
