Solve for n if s = 540 Enter the value in the box. 180(n − 2) = s

netineya [11]

Answer:

n = 5

Step-by-step explanation:

180(n − 2) = s

180(n − 2) = 540

180n - 360 = 540

180n - 360 + 360 = 540 + 360

180n = 900

(1/180) 180n = 900 (1/180)

n = 5

lawyer [7]

Answer:

$389.35

Step-by-step explanation:

A certain computer costs $599.00 at Best Buy. On Black Friday, it is on sale for 35% off.

So, after 35% off the price of the computer will reduce from $599.00.

We are asked to find the cost of the computer on Black Friday.

Therefore, the price of the computer will reduce by $[599 \times \frac{35}{100}] = 209.65$ Dollars.

And the reduced price on the Black Friday will be $(599 - 209.65) = $389.35 (Answer)
