porfavor lo necesito para hoy!!​

Answer 1

Explicación paso a paso:

5)

•camisa : 240.20 (20/100) = S/ 48.04

•pantalon: 290.50(20/100) = S/ 58.1

• Campera: 350(20/100) = S/ 70

• zapatillas : 315.70(20/100) = S/. 63.14

6)

a) 40%X = 1500

(40/100)X = 1500

0.40X = 1500

X = 1500/0.40

X = 3750

b) 75%X = 6000

(75/100)X = 6000

0.75X = 6000

X = 6000/0.75

X = 8000

c) 125%X = 120

(125/100)X = 120

1.25X = 120

X = 120/1.25

X = 96

Entonces :

• 25% de 96

(25/100)96

(0.25)96

24

d) 20%(X+ 15) = 29

(20/100)(X+15) = 29

0.20(X + 15) = 29

X + 15 = 29/0.20

X + 15 = 145

X = 145 - 15

X = 130
