3) A long street has 100 buildings that are numbered from 1 thru 100.
How many 9's are used in numbering the buildings?

4) A Fruit stand sells apples for $1 each. Each apple is wrapped in a special gold wrapper. You can then trade in 3 gold wrappers for 1 apple. If you had $15 to spend, How many apples can you get altogether?

1.) You add another cow so that there's eighteen. The oldest gets nine, the middle one gets six, and the youngest gets two. The person who donated the eighteenth cow gets it back, as 9+6+2=17.
2.) In Roman numerals, 29 is XXIX. You take the I away, you get XXX, or 30.
3.) Twenty. 9, 19, 29, 39, 49, 59, 69, 79, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99.
4.) You can get 21 apples. You buy 15 apples with your $15. You can trade in your 15 wrappers for 5 more apples. You can then trade in 3 of those 5 wrappers for another apple.
