Answer:
157.5.
Step-by-step explanation:
If the 6-inch pizza has 630 calories, the 12-inch pizza has double.
6 x 2 = 12.
Therefore, the 12-inch pizza has 1,260.
630 x 2 = 1,260.
There are 8 slices in a pizza, making the answer 1,260 / 8.
1,260 / 8 = 157.5
An estimation could be 150 if you round 630 to 600.
Hope this helps!
