Find the domain and range of the relation. use interval notation where appropriate.
a. domain: (–∞, 3); range: [–1, ∞)
b. domain: (–∞, 3); range: [–1, ∞]
c. domain: [–∞, 3); range: [–1, ∞)
d. domain: [–1, ∞); range: (–∞, 3)

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
