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?(1 point

The total cost of everything is $325 + $250 + $375 = $<<325+250+375=950>>950.

The cost of Shardell's portion is $950 / 2 = $<<950/2=475>>475.
The amount of state tax on Shardell's portion is $475 * 9% = $<<475*9*.01=42.75>>42.75.
The total cost for Shardell's portion is $475 + $42.75 = $<<475+42.75=517.75>>517.75. Answer: \boxed{517.75}.
