answer:

D

Step-by-step explanation:

Why its D is because you have to plug in x to get y and you can eliminate A and B because what ever you plug in a x number you would get a negative number for y. Then your left with two answers C and D you can start plugging in x values now for 4 for C you get 4.105(4) = 16.42 - 1.560 = 14.86 which is not even close to 3. Now for 4 for D you get 1.560(4) = 6.24 - 4.105 = 2.135 which is the closest answer out of all those equations to 3. To make sure it true if you keep plugging in x values it would give you answers to close to the y values. Hope this helps.

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio
