Answer:
169 farmers raised chickens last year.
Step-by-step explanation:
Given that:
Number of farmers raising chickens this year = 220
This is 30% more than previous year.
Let,
100% be the percent of previous year and x be the number of farmers who raised chicken previous year.
Percent of farmers who raised chickens this year = (100+30)% = 130%
130% of x = 220
[tex]\frac{130}{100}x = 220[/tex]
1.3x = 220
Dividing both sides by 1.3
[tex]\frac{1.3x}{1.3}=\frac{220}{1.3}\\x=169.23[/tex]
Rounding to nearest whole number
x = 169
Hence,
169 farmers raised chickens last year.
