o-na [289]
Since it’s 35% off, but there’s a 8% tax,
35 - 8 = 27%

You get a 27% discount.

There is an animal farm where chickens and cows live. All together, there are 84 heads and 210 legs. How many chickens and cows
Ira Lisetskai [31]

1 Chicken have = 2 legs

1 Cow have = 4 legs

No of cows = x

No of chickens = y

Total no of legs = 4x + 2y = 210.............(1)

Total No of heads = x + y = 84................(2)

x = 84 - y....( from (2) )

Substituting the above equation in (1)

4 ( 84 - y) + 2y = 210

336 - 4y + 2y = 210

336 - 2y = 210

-2y = -126

= y = 63

No of cows = 84-63 = 21

∴ <u><em>Total no of cows = 21</em></u>

<u><em>Total no of chickens = 63</em></u>
