Economics is the study of mankind in the ordinary business of life --Alfred Marshall Norman

Your group is building a new zoo. You have to decide what animals to have. Space is limited. You get 25 acres. Take 8-10 minutes to make your selections, based on the next slide.

Lion - 2 acres Turkey - 1/10 acre Giraffe -1 acre Seal - 1/2 acre Camel - 1/2 acre Cheetah - 1 acre Cow - 1/3 acre Monkey - 1/2 acre Asian Elephant - 1 acre African Elephant acres Reptile House - 5 acres Hammerhead Shark - 1/2 acre Kangaroo - 1/2 acre Tiger - 1 acre Whales - 3 acres House of Birds - 5 acres hint:they don’t like being alone *Numbers are acres required for ONE animal (hint: they don’t like being alone!) over 34 you will have to make choices [ If you had 2 of each, it would take over 34 acres –so you will have to make choices.]

Lion - 2 acres; Turkey - 1/10 acre; Giraffe -1 acre; Seal - 1/2 acre; Camel - 1/2 acre; Cheetah - 1 acre; Cow - 1/3 acre; Monkey - 1/2 acre; Asian Elephant - 1 acre; African Elephant acres; Reptile House - 5 acres; Hammerhead Shark - ½ acre; Kangaroo - 1/2 acre; Tiger - 1 acre; Whales - 3 acres; House of Birds - 5 acres. hint: they don’t like being alone! *Numbers are acres required for ONE animal (hint: they don’t like being alone!) over 34 acres you will have to make choices [If you had 2 of each, it would take over 34 acres – so you will have to make choices.]

Two tigers Two seals Two Asian elephants Two monkeys To get you started here are some examples of what you might do! This would have taken care of 7 of the 25 acres. 18 more to go! Two camels R emember that 2 of each helps future zoo stock.
