SQL Server - SUM(Column) * QtyColumn

Question

Is it possible to get the total without returning it in multiple rows (Group BY)?

Example:

Data:

ID    Amount   Quantity
1     50       1 
2     50       2

select sum(Amount) * Quantity, SUM(Quantity) as totalQuantity 
  from tbl

I want the results to be in 1 row:

total       totalQuantity 
150         3

Answer 1

Here you go

SELECT SUM(Amount*Quantity) as total, SUM(Quantity) as totalQuantity

Answer 2

select sum(Amount * Quantity) as total, 
       sum(Quantity) as totalQuantity
from your_table
