Answer:
Step-by-step explanation:
A straight line that has one independent variable and one dependant variable.
To minimize the cost, we take the straight distance from the refinery to the other side of the river as 2 km. Also, the 7 km will be the distance that has to be traveled by the pipeline in land. The total cost, C, is therefore,
total cost = (2 km)($800,000/km) + (7 km)($400,000 /km)
total cost = $4,400,000
Thus, the total cost of the pipeline is approximately $4,400,000.00.
Yes because if you divide both, the numerator and denominator, by 7 it would simplify to 10/3, so they are equivalent.
