Answer:
$61.75
Step-by-step explanation:
I divided the $42.75 by 9 to get 4.75. Then i multiplied the 4.75 by 13 to get $61.75.
27ft³=x tons
1ft³=0.5 tons

Cross multiply
1x=13.5tons
x=13.5tons
So one scoop/load carries 13.5 tons of sand. Lets see how many 120 loads can carry.
13.5tons*120loads=1620 tons of sand
Now lets see how freight cars it would take to hold 1620 tons of sand
1620/40=40.5 freight cars
Since you can't have .5 of a freight car, lets round 40.5 up to 41
Answer=41 freight cars
