Let's summarize the information about the pizzas:
-
Pepperoni Pizza:
- Total slices: 10
- Slices eaten: 7
- Slices remaining: 10 - 7 = 3
-
Cheese Pizza:
- Total slices: 20
- Slices eaten: 13
- Slices remaining: 20 - 13 = 7
-
Mushroom Pizza:
- Total slices: 8
- Slices eaten: 5
- Slices remaining: 8 - 5 = 3
Now, if we want to know the total number of slices eaten and the total remaining:
-
Total slices eaten:
- Pepperoni: 7
- Cheese: 13
- Mushroom: 5
- Total Eaten = 7 + 13 + 5 = 25
-
Total slices remaining:
- Pepperoni: 3
- Cheese: 7
- Mushroom: 3
- Total Remaining = 3 + 7 + 3 = 13
So, in total, 25 slices were eaten, and 13 slices remain.
