"old macdonald had a farm." but on his farm, he only raised pigs and chickens - 48 of them all together. one day, he noticed that the total number of heads and wings was equal to the total number of feet. how many pigs and how many chickens did old macdonald have on his farm?

Chickens have  2 wings and 2 feet and 1 head
pigs have 0 wings and 4 feet and 1 head

c+p=48

c+p+2c=2c+4p
3c+p=2c+4p
minus 2c+p both sides
c=3p
subsitute 3p for c in other equation

c+p=48
3p+p=48
4p=48
divide 4
p=12
sub back

c=3p
c=3(12)
c=36

12 pigs
36 chickens

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
