Problema Solution
John's pizza sells one 16-inch cheese pizza or two 10-inch cheese pizzas for $10.99. Determine which size gives more pizza
Answer provided by our tutors
Two 10-inch pizzas having price each of one is 3.33$
and one 16-inch pizza having price 4.33$
area of a circle: A=PIr^2
area of the 10-inch pizza is 314 square inches
area of a 16-inch pizza is 804 square inches
calculate the "square inches per dollar" for each pizza scenario:
2*(314)/3.33 = 188
(804)/4.33 = 185
you get more pizza (804 in^2 compared to 618 in^2) if you buy the 16-inch pizza but it is cheaper (188 square inches per dollar) to buy the two 10-inch pizzas instead of one 16-inch pizza (185 square inches per dollar)
