Question

1. Maria Eduarda bought a blouse and pants and spent R $ 96.00. Knowing that the pants cost R $ 16.00 more than the blouse, determine how much Maria Eduarda paid for each piece.

Answer 1

Resposta:

Blouse: R$40

Pants: R$56

Explicação passo-a-passo:

B ----> blouse

P ----> pants

(I)   B + P = 96

(II)  P = 16 + B

(II) em (I):

B + (16 + B) = 96

2B = 96 - 16

2B = 80

B = 80/2

B = 40

(I): B + P = 96

40 + P = 96

P = 96 - 40

P = 56
