Question

This year, there are 220 farmers raising chickens in the county. This is a 30% increase over last year. How many farmers raised chickens last year?

Answer 1

169 farmers raised chickens last year.

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

`(130)/(100)x = 220`

1.3x = 220

Dividing both sides by 1.3

`(1.3x)/(1.3)=(220)/(1.3)\\x=169.23`

Rounding to nearest whole number

x = 169

Hence,

169 farmers raised chickens last year.
