Question 572195: You and seven of your friends (8 people total)order a pizza frOm Dominios for $2.00 per person. It has a 18 inch diameter. You split the pizza evenly between all of you
You and three of your friends (4people total) each order 3 slices of pizza from Pizza Hut for $5 total per person. Each slice is 1/8 of a pizza with a 19 inch diameter
Which deal is better?
Your help will be greatly appreciated.
On my own I discovered that:
Dominos pizza will feed eight people for the cost of $16.00 and I estimated that each slice will be 2.25inches
Pizza huts pizza will feed. Four people for the cost of $15.00 and will provide 12 slices at 2.375 inches per slice
