The farmer

The farmer harvested 840 tons of grain in 2006, which was 44% less than in 2005, and one-fifth more than in 2004. How many tons of grain harvested in years 2005 and 2004?

Correct answer:

x =  700 t (2004)
y =  1500 t (2005)

Step-by-step explanation:

840=(1+1/5)x x=1+1/5840=700 t 840=(144/100)y y=1+44/100840=1500 t

840 = (1-44/100)y
840 = (1+1/5)x

840 = (1-44/100)•y
840 = (1+1/5)•x

56y = 84000
6x = 4200

x = 700
y = 1500
