Well the greatest number of groups is 35 groups of 1, but some other group sizes are 7 groups of 5 and 5 groups of 7.
<em><u>Division equation is:</u></em>

There are 2816 calories in whole pizza
<em><u>Solution:</u></em>
Given that,
A 14- inch pepperoni pizza is sliced into 8 equal pieces
One slice contained 352 calories
Therefore,
1 slice = 352 calories
Let "c" be the calories
Given that there are 8 equal pieces
<em><u>Therefore, calories in 8 pieces are:</u></em>
Calories in 8 pieces = 8 x calories in 1 piece

Thus the division equation is:

Therefore,

Thus there are 2816 calories in whole pizza
The answer to your question is 8, y=8
Range is the difference beteeen the smallest and largest numbers in a set.
Therefore, 50-32=18
