Iam thinking of a number. if you multiply my number by 5, add -12 to the product, and then take 1/2 of the sum, the result is 14. find my number.

14x2=28

28+12=40

40/5=8

(2n - 12)/2 = 14

Five times the number subtracted by 12, divided by 2 is equivalent to 14.

Multiply both sides by 2:

2n - 12 = 28

Add 12 to both sides:

2n = 40

n = 20

The number is 20

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
