 +-----------+   The tell-all receipt         
 | THANK YOU |
 |CALL AGAIN |   I recently found this receipt. I tried remembering a 
 |           |   few things that I had bought (I only go shopping on my
 |0521.94    |   birthday once a year) and was surprised at the amount
 |           |   of information I could get from it. Work with your
 |   3.79 *1 |   team and your NTP to answer these questions:
 |   3.26  2 |
 |     13    |   1) How many items did I buy?
 |   0.34  @ |
 |   4.42  3 |   2) How much did I pay for the most expensive item?
 |   2.35 *4 |
 |   0.25 CR |   3) How much was the least expensive item?
 |  14.33ST  |
 |   6.14 TA |   4) Did I get any money for the bottle I took?
 |   0.51TX  |
 |  20.33AT  |   5) What's the sales tax rate in El Paso?
 |   6.00CG  |
 |           |   6) What day of the week was it? What Julian date was it?
 |  No 971   |
 |   20.03   |   7) Why do some items have an asterisk?
 +-----------+
                 8) How did I pay?

                 9) If I live 8 minutes away from the grocery store, did
                    I make it back on time for the 8:00 news?
