Answer:
for brand a= $8 per/kg and brand b=$5 per/kg
Step-by-step explanation:
Let A be the cost per kg. of brand a
Let B be the cost per kg. of brand b
forming the equation: (wt. * cost + wt. * cost = wt. * cost)
4A + 6B = 10(6.20)
------(1)
2A + 8B = 10(5.60)
------(2)
lets find out the values of A and B by solving above equations.
(1)=>
put this value in eq(2)
(2)=>
= 5 ---> ($5 per/kg for B)
now for A,
=8 ---> ($8 per/kg for A)
