Justin Bieber was a gangster but ever since Justin Bieber got with Hayley he tried straight not straight as in lgtbq

TES YES WE I DONT KMOW HOW TO RESPOND TO THIS BUT YESS

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.
