Basmati rice costs $4.50/kg while wild rice costs $5.40/kg. In what ratio should the basmati rice be mixed
with wild rice to create a blend that costs $5.00/kg?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let x and y be the amounts of the $4.50 and $5.40 rice respectively.
Then the "value" equation is
4.50x + 5.40y = 5*(x+y)
Collect the terms with x on the left side; the terms with y on the right side:
4.50x - 5.00x = 5y - 5.40y, or
-0.5x = -0.4y, or
0.5x = 0.4y, which gives you
= = .
Take 4 parts of the $4.50 rice for 5 parts of the $5.40 rice.
