The scale factor of the dimensions of two similar wood floors is 5 : 4. it costs $384 to refinish the smaller wood floor. at that rate, how much would it cost to refinish the larger wood floor?

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

.75

Step-by-step explanation:

1000-250=750

750/1000 = 3/4

3/4 = .75
