A store is having a sale on jelly beans and almonds. For 6 pounds of jelly beans and 2 pounds of almonds, the total cost is $12
CaHeK987 [17]

Solution:

Let each pond of  jelly beans cost $x.

and each pond of almonds cost $y.

Then we can write

6x+2y=12.......(i)

3x+5y=15.....(ii)

Now solve these two equations together using substitution we get

3x=15-5y

30-10y+2y=12\\
\\
-8y=12-30\\
\\
-8y=-18\\
\\
y=2.25\\
\\
3x=15-5y=15-5*2.25=3.75\\
\\
x=1.25

Hence each pond of jelly bean cost 1.25$

Each pond of almond costs 2.25$
