The Powerball jackpot will grow again as nobody matched all six numbers in last night’s drawing, worth nearly 200-million dollars. Two tickets sold in Iowa matched five of the six numbers though, and the Iowa Lottery’s Mary Neubauer says those tickets are worth six-figures each.The 100-thousand dollar tickets were sold in Davenport and Des Moines. Neubauer says the big prize Saturday will be worth 280-million dollars, maybe more depending on ticket sales. Neubauer says the largest jackpot in Powerball history was 295-point-seven million dollars, given away to a pool of 13 Ohio workers in 1998. The Saturday jackpot could exceed 280-million dollars — a number she tries to put in perspective.It’s almost enough for one dollar for every person in America, as the 2000 Census finds 281-million people live in the U-S. Neubauer says there’s always a chance someone from Iowa will win the big Powerball prize.She says 280-million dollars is enough to give every man, woman and child in the state 95-dollars each. What else could you do with all that dough? Neubauer says you could take 280-million one-dollar bills and lay them end to end and easily circle the earth — with more than 2-thousand extra miles of money.
