At Pizza Delight in Halifax the prices are:
(i) one 6” pizza for $4.99
--
Area = (pi)3^2 = 9pi sq inches ; price per sq.in = 499/(9pi) = 17.65 cents
--------------------------------------------------
(ii) two 6” pizza for $7.49,
Area = 2*9pi = 18pi sq inches ; price per sq.in = 749/(18pi) = 13.25 cents
------------------------------------------------------
(iii) one 9” pizza costs $7.99.
Area = (4.5)^2(pi) = 20.25(pi) sq. in. : ppsi = 799/(20.25pi) = 12.56 cents
--------------------------
Which are the best and the worst deal.
Best is one 9"
Worst is one 6"
