I think the answer is 4.5%
D. 28
this is because 48 divided by 12 is 4, 4 times 7 is 28.
The total weight being carried is
3545 +1758 +3697 = 9000 . . . . . pounds
Each ton is 2000 pounds, so together the trucks are carrying
(9000 lb) × (1 t)/(2000 lb) = 4.5 t
Altogether, the 3 trucks are carrying 4.5 tons of topsoil.
