College algebra word problem?
The U.S. Maritime Administration estimated that the cost per ton of building an oil tanker could be represented by the model y =109,000 / (x + 230) , where y is the cost in dollars per ton and x is the tons (in thousands). What size of oil tanker (in thousands of tons) can be built for $350 per ton?
Comments
y =109,000 / (x + 230)
350 =109,000 / (x + 230)
350(x + 230) = 109,000
350x + 80,500 = 109,000
350x = 28,500
x = 28,500/350
x = 81.4
At $350 per ton an oil tanker of 81.4 thousand (81,400) tons can be built.
350 = 109000/(x + 230)
solve for x
