2 metros de tela cuesta $ 4,25 cuánto cuesta 7,5 m;8 m y 9,4m.

Answer 1

Respuesta:

7.5m = $15.93

8m = $17

9.4m = $19.97

Explicación:

Usando regla de 3:

2m -> $4.25

7.5m -> x

x = (7.5 • 4.25) / 2

x = $15.93

2m -> $4.25

8m -> x

x = (8 • 4.25) / 2

x = $17

2m -> $4.25

9.4m -> x

x = (9.4 • 4.25) / 2

x = $19.97
