At the market you can buy a cow for $10, a pig for $1 and 8 hens for $1. How many animals would you need to buy to get 100 mixed animals for exactly $100?
7 cows, 21 pigs and 72 hens. The trick to this is finding the combination of cows and hens with the same cost and quantity since pigs are already equal. The magic combination is 7 cows and 72 hens, giving you 79 animals that cost $79 ($70 + $9). Then you just add 21 pigs to get to 100 animals.
Credit or debt. Debt is a problem in many people’s lives, but in order to go to school or make a large purchase, it can be useful. As your debt grows older, it’s more unpleasant than useful.
The next number in the sequence is n squared minus m or f(n,m) = n2 – m f(6,9) = 62 – 9 = 27 f(9,27) = 92 – 27 = 54 f(27,54) = 272 – 54 = 675 f(54,675) = 542 – 675 = 2241
The moon. The moon has been around for quite some time, but there’s a “new” moon every month or so. A Blue moon is a rare event. The moon is a body of rock, so it’s never empty, but we do see what we call a full moon some nights. And the moon’s gravity “pulls” on the ocean to create low and high tides, but it doesn’t push anyone around because it’s a friendly fellah.
I hide in the daylight but prefer the sun, I have no fingers but can hold a gun, I have three eyes but cannot see, I live on land but in a tree, I’m spotted in pink and cannot grow, When you look away is when I show.
