Answer:
The afrmer had 480 chickens at first
Step-by-step explanation:
We make an assumption here, that the initial number of chickens that the farmer has, is C.
Chickens sold by the farmer is (20% of C) + 240 chickens
Number of chickens left after selling in the morning and afternoon is 30% of C
So, the first number of chickens = Number of chickens sold + Number of chickens left
This gives us an equation that will be solved to obtain C.
C = ([tex]\frac{20}{100}[/tex] × C) + 240 chickens + ([tex]\frac{30}{100}[/tex] × C) = 0.2C + 240 chickens + 0.3C
C = 0.5C + 240 chickens
C - 0.5C = 240 chickens
0.5C = 240 chickens
C = [tex]\frac{240 chickens}{0.5}[/tex]
C = 480 Chickens
