我不太确定我的代码在哪里导致导致错误计算的问题.当我运行该程序时,会出现以下警告:

C4305:'argument':从'double'截断到'float'.

税额(ta)和总成本(tc)似乎有问题,

Current Output:
Cost before Tax: $30.20
Tax Amount: $30.20     
Total Cost: $-107374144.00
ground beef is ex-sponged
Press any key to continue . .


What it **should** be:
Your item name:ground beef
Cost before Tax: $30.20
Tax Amount: $2.64
Total Cost: $32.84
ground beef is ex-sponged
