Shardell and Marsha are planning a party. Since they are both hosting, they have agreed to split the cost for everything in half. The catering bill is $325, the venue bill is $250, and the DJ is $375. If state tax is 9%, what will

Shardell's portion cost?

Shardell's portion will cover half of the total cost of everything.

First, calculate the total cost of everything: $325 + $250 + $375 = $<<325+250+375=950>>950

Then calculate the total cost including tax: $950 * 1.09 = $<<950*1.09=1035.5>>1035.5

Finally, calculate Shardell's portion by dividing the total cost including tax by 2: $1035.5 / 2 = $<<1035.5/2=517.75>>517.75. Answer: \boxed{517.75}.
