In one month a store had 1,222 in sales but exspenses were 2,345. how much did the store lose in that month

The store starts out as 0 profit

The store than made 1222 sales ( 0 +1222) = 1222

however, the store spent 2345  ( 1222- 2345) = -1123

The store lost 1123 (dollars? idk what the thing is, but the store lost 1123 of whatever that is)

hope this helps
