You can put this solution on YOUR website! How many pounds of hamburger that costs 1.60 per pound must be mixed with 70 pounds of hamburger that costs 2.10 per pound to make a mixture that costs 1.70 per pound?
Here is the set up:
[first mixture] + [second mixture] = [total mixture]
[x(1.60)] + [2.10(70)] = [1.70(x + 70)]
We are looking for x.
x1.60 + 147 = 1.70x + 119
x1.60 - 1.70x = -147 + 119
-0.1x = -28
x = -28/-0.1
x = 280
How many pounds of hamburger that costs 1.60 per pound must be mixed?
The answer is 280 pounds.
