the manager of a farmer market has 500 lb of grain that costs 1.20 per pound. how many pounds of meal costing .80 per pound should be mixed with the 500 lb of grain to produce a mixture that costs 1.05 per pound
----------------------
Equation:
value + value = value
1.20*500 + 0.80x = 1.05(500+x)
Multiply thru by 100 to get:
120*500 + 80x = 105*500 + 105x
25x = 15*500
x = (3/5)(500
x = 300 lbs. (amt. of 80 cent meal needed in the mixture)
