Question

Paso a paso, por favor

Answer 1

Respuesta:

1) $674

2) $166

Explicación paso a paso:

5 pasteles de fresa y 3 de piña cuestan $2530 = 5 fresa + 3 piña = $2530

4 fresa + 5 piña = $586 + $2530 = $3116

Entonces:

5 fresa + 3 piña = $2530... (1)

4 fresa + 5 piña = $3116... (2)

Multiplicamos (1) × 5 y (2) × -3

25 fresa + 15 piña = $12650

- 12 fresa - 15 piña = - $9348

Eliminamos piña...

25 - 12 fresa = $12650 - $9348

13 fresa = $3302

fresa = $254

Reemplazamos en (1):

5 fresa + 3 piña = $2530

5 × $254 + 3 piña = $2530

3 piña = $1260

piña = $420

Entonces:

A) $254 + $420 = $674

B) $420 - $254 = $166
