The original price of a sofa is £6000. If it's value is £2406.45 after 5 years find the depreciation rate. Give your answer to 1 decimal place.

1) If  2x > 50 , then x > 25.  Draw a circle at x=25 and then extend a ray in the positive x direction away from x = 25.

2) If x + 6 < 32, subtract 6 from both sides, obtaining x < 26.
     Draw a cirlce at x=26 and extend a ray from that x to the left.
