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
384 / 4 = 96 dollars
96 dollars per unit of the ratio
now to get the price to refurbish the larger wood floor, times the price by the units
96 * 5 = 480
