I don't know for a fact but I think k=1.125
The answer should be -14(2+v^6) if I’m correct
If the truck is 14,000 pounds and increases by 2 tons yes. However if it is above 14,000 then no it will not be a class 4 truck.
2.50-2.00=0.5
2.50/0.5= 5 = 100%
2.00/0.5=4 = 80%
100-80= 20%
25% of 8 is 2, 8-2=6
2 are red, 6 are blue
