Six friends want to buy pizza and need to decide between two deals. The first deal is for two pizzas for $7.00 each for a pizza with a 10 inch diameter. Or a second deal with one pizza with a 14 inch diameter for $15.00. The friends decide to buy the offer with the most pizza for each person. How do I solve for the six of each?
