Un grupo de amigos quiere realizar una actividad de recaudación de fondos, para ello han decidido vender pizzas. La primera pizz
trasher [3.6K]

Answer:

Los Amigos deberían comprar pizzas vendidas por la primera pizzería que cuestan S / 0.032 por cm² para obtener más ganancias.

Step-by-step explanation:

Los parámetros dados son;

El diámetro de las pizzas vendidas por la primera pizzería = 40 cm

El precio de las pizzas vendidas por la primera pizzería = S / 40

El diámetro de las pizzas vendidas por la segunda pizzería = 25 cm

El precio de las pizzas vendidas por la segunda pizzería = S / 25

El área de las pizzas vendidas por la pizzería = π × D² / 4

El área de las pizzas vendidas por la primera pizzería = π × 40² / 4≈1256.64 cm²

El costo por unidad de superficie de las pizzas vendidas por la primera pizzería = S / 40 / (1256.64 cm²) ≈ S /0.032/cm²

El área de las pizzas vendidas por la segunda pizzería = π × 25² / 4≈490.87 cm²

El costo por unidad de superficie de las pizzas vendidas por la primera pizzería = S / 25 / (490.87 cm²) ≈ S /0.051/cm²

Las pizzas vendidas por la primera pizzería que cuestan S /0.032/cm² s más baratas y producirán mejores ganancias que las pizzas vendidas por la segunda pizzería que cuestan S /0.051/cm²

Por lo tanto, los amigos deben comprar pizzas vendidas por la primera pizzería que cuestan S /0.032 / cm² para obtener más ganancias.
