walnuts that cost $4.05 kilogram were mixed with cashews that cost $7.25 per kilogram.How many kilograms of each were used to make a 50 kilogram mixture that costs $6.25 per kilogram. ROUND each to the nearest tenth.
------------------------------------
The quantities are "x" and "50-x" and total amount of 50.
The values are 4.05x and 7.25(50-x) and 6.25(50)
------------------------
Value equation:
value + value = value
4.05x + 7.25(50-x) = 6.25*50
405x + 725(50-x) = 625*50
405x + 725*50 - 725x = 625*50
-320x = -100*50
x = 15.625 kg of walnuts
50-x = 34.375 kg of cashews
=============================
Cheers,

this being algebra.com...let's use an equation...
let x="kg of walnuts", so 50-x="kg of cashews" __ 50 kg total, right?
4.05(x)+7.25(50-x)=6.25(50) __ 4.05x+362.5-7.25x=312.5 __ -3.2x=-50 __ x=15.6
50-x=34.4
