You have just bought a new sony 55" 3d television set for 1750 the value of the television set decrease by 220 per year how long before the television set is worth half of its original value

Answer 1

1750-220t = 1750/2 = 875

220t = 1750-875 = 875

t = 875/220 = about 3.977 years = about 4 years

or 3 years 11 months 21 days, 19 hours, 38 minutes, 10.9 seconds

go with 4 years

4 x 220 = 880

1750-880 = 870 = slightly less than half it's purchase price
