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
Correct answer: 6/5 or 1 and 1/5 or 1.2 (pick your favorite form)
This actually technically can't be answered without more information as all we know is that the point (250, 300) exist somewhere on this function describing royalties. However, it is safe to assume that James earns $0 when he is selling 0 books, so the point (0,0) also exists.
Using this information, the formula for slope (rate of change) is rise over run, more mathematically expressed m = (y_2 - y_1) / (x_2 - x_1)
In this case, m = (300 - 0) / (250 - 0) = 300/250 = 6/5 = 1.2
