Can you add the picture so I know what it is.
Answer:
275 non spectators
Step-by-step explanation:
1. Subtract
42,500 - 31,750 - 10,475 =
275
2. Get answer
275 non-spectators
80% of 20 is 80/100 x 20 = 16
So, kelly has used 16 stamps, and has 4 left
792/22=36
You can represent this as a subtraction problem as well.
792-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22-22=36
Addition: 792=22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22+22
Multiplication:
792=22*36
