How can a kid get 100 dollars in 1 day?

Answer 1

Oh, dude, easy peasy lemon squeezy. They can do some chores around the house, like cleaning, mowing the lawn, or walking the neighbor's dog. Or they could try selling some old toys or clothes online. But hey, if all else fails, they could always try their luck at finding a winning lottery ticket on the sidewalk.

Answer 2

Hard work; cut grass, rake leaves, shovel snow.
