Ms. Jackson + her 3 friends = 4 people all together
Find how many would each person be getting/eating.
6 rolls / 4 people = 1.5 roll(s) a person
First, subtract 3.75 from 70.50.
70.50 - 3.75 = 66.75
Take 66.75 and divide that by 4 (people)
66.75 / 4 = ~ (about) 16.69
Lastly, take 16.69 and divide that by 1.5 (roll(s))
16.69 / 1.5 = ~ (about) 1.11 each roll
I'm not sure that is right but I tried :(: I hope this works and is right! :) Sorry if it isn't! :(
