A wild birdseed mix is made by combining 100 lb of millet seed costing $.60 per pound with sunflower seeds costing $1.10 per pound. How many pounds of sunflower seeds are needed to make a mixture that costs $.70 per pound?
----------------------
Value Equation:
value + value = value
60*100 + 110x = 70*(100+x)
6000 + 110x = 7000 + 70x
40x = 1000
x = 25 lbs (Amount of sunflower seed mix needed)
