Your parents gave you $50 to take your brother and sister to the movies. Your ticket cost $8.25 and your siblings cost $4.25. If you spent an additional $20 on soda and popcorn, how much money did you bring home with you? $50 $39.75 $13.50 $13.25

OpenStudy (sloppycanada):

8. 25 + 8.50 + 20 = ?

OpenStudy (anonymous):

36.75

OpenStudy (sloppycanada):

50 - 36.75?

OpenStudy (anonymous):

13.75

OpenStudy (sloppycanada):

No.

OpenStudy (sloppycanada):

Close, but no. If I added 13.75 + 36.75 I would get 50.5

OpenStudy (sloppycanada):

This means I somehow had an extra fifty cents lying around somewhere. Which didn't happen according to this problem. Mom gave us 50$, not 50.5$.
