Chickens have 1 head and 2 legs
rabbits had 1 head and 4 legs


total heads is 30
c+r=30
total legs is 98
2c+4r=98
divide by 2
c+2r=49

multiply top equation by -1 and add to 2nd equation

-c-r=-30
<u>c+2r=49 +</u>
0c+1r=19

r=19

sub back
c+r=30
c+19=30
minus 19
c=11

11 chickens

anyanavicka [17]
------------------------------------------------------------------------------------------------------
Find the cost of the first 10 hours:
------------------------------------------------------------------------------------------------------
10 hours = $220 x 10
10 hours = $2200

------------------------------------------------------------------------------------------------------
Find the cost of the next 5 hours (only the second mechanic worked):
------------------------------------------------------------------------------------------------------
5 hours  = $2725 - $2200 
5 hours = $525

------------------------------------------------------------------------------------------------------
Hourly charge of the second mechanic:
------------------------------------------------------------------------------------------------------
5 hours = $525
1 hour = $525 ÷ 5
1 hour = $105

------------------------------------------------------------------------------------------------------
Hourly charge of the first mechanic:
------------------------------------------------------------------------------------------------------
$220 - $105 = $115


------------------------------------------------------------------------------------------------------
Answer: First mechanic = $115/hour ; Second mechanic = $105/hour
