The u. s. maritime administration estimated that the cost per ton of building an oil tanker could be represented by the model y=104,000/x+235 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? a. 62 thousand tons b. 6 thousand tons c. 532 thousand tons d. 178 thousand tons

(c)

substitute x = 350 into the equation for y

y = + 235 ≈ 532 000

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
