The daily average sales of pastries amounts to 20 pastries * $2/pastry = $<<20*2=40>>40.
The daily average sales of bread amounts to 10 loaves of bread * $4/loaf = $<<10*4=40>>40.
Therefore, the daily average is $40 + $40 = $<<40+40=80>>80.
Today’s sales of pastries amounts to 14 pastries * $2/pastry = $<<14*2=28>>28.
Today’s sales of loaves of bread amounts to 25 loaves of bread * $4/loaf = $<<25*4=100>>100.
Therefore, today’s sales amount to $28 + $100 = $<<28+100=128>>128.
This means the total difference between today’s sales and the daily average is $128 – $80 = $<<128-80=48>>48.
