Question 1011096: The sun ocean company wants to lay down pipes under that will connect an on shore site to an off shore site. These two sites are 15 miles apart (by land) and the off shore site is 6 miles out in the water. Pipes that are laid under water cost 500,000$ and pipes that are laid underground cost 100,000$.

You can put this solution on YOUR website!
x, length under water
y, length under ground

system%28x%2By=15%2Cx=6%29, "offshore" for the x value.

y=9-----Now you can find the cost for the two parts.
500000%2A6%2B100000%2A9
