Answer:
C = 125S + $3750
Step-by-step explanation:
$ 3750 Â = truck rental; Â $125 per ton of sugar transported. Â C is the cost; Â S is the number of tons transported. The equation relating C to S would be a linear equation like y = mx + b. This equation would be graphed in the first quadrant only. You would start with your y-intercept at (0, 3750). As x increases by 1, your y increases by 125 yielding these points:
(1, 3875) Â (2, 4000) Â (3, 4125) Â etc.
This shows that for each increase by one ton of sugar, the cost goes up $125
