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)
Hi there!
To add fractions there are three simple steps:
1. Make sure the bottom numbers (denominators) are the same. → In your case you're all good, both your denominators are 8.
2. Add the top numbers (numerators) and put that answer over the denominator :
-3 + 7 = 4 →
3. Simplify the fraction (if needed). → In your case, you do need to simplify your fraction :
Divide both your numerator and denominator by 4 to get your simplified fraction :
4 ÷ 4 = 1
8 ÷ 4 = 2
Your simplified fraction is :
There you go! I really hope this helped, if there's anything just let me know! :)
