Answer:
El costo de cada artículo es:
chocolate: $8
dulce: $5
Explanation:
1c + 2d = 18
3c + 1d = 29
c = costo de cada chocolate
d = costo de cada dulce
Al multiplicar por -3 la primer ecuación y sumarla con la segunda ecuación:
-3c - 6d = -54
3c + 1d = 29
0 - 5d = -25
-5d = -25
d = 25/5
d = 5
1c + 2d = 18
1c + 2*5 = 18
c + 10 = 18
c = 18 - 10
c = 8
Comprobación:
3c + 1d = 29
3*8 + 5 = 29
24 + 5 = 29
