The 12 portions weigh a total of 12*0.7 = 8.4 lbs
So, the almonds weigh 8.4 - 3.6 = 4.8 lbs
I NEED ANSWER
The 12 portions weigh a total of 12*0.7 = 8.4 lbs
So, the almonds weigh 8.4 - 3.6 = 4.8 lbs
(3.6+x)/12 = 0.7
3.6+x = 8.4
X =
We know that she mixes 3.6 pounds of almonds with some raisins. So the weight of the trail mix is 3.6 pounds + the weight of the raisins. Let's call the weight of the raisins "r".
The total weight of the trail mix (including almonds and raisins) is divided into 12 equal portions, with each portion weighing 0.7 pounds. Therefore, the weight of the trail mix is equal to 12 portions multiplied by 0.7 pounds per portion:
12 portions * 0.7 pounds/portion = 8.4 pounds
Now we can set up an equation to solve for the weight of the raisins (r):
3.6 pounds (almonds) + r (raisins) = 8.4 pounds (total trail mix weight)
To find the value of r, we need to isolate it on one side of the equation:
r = 8.4 pounds - 3.6 pounds
r = 4.8 pounds
Therefore, Ingrid used approximately 4.8 pounds of raisins to make the trail mix.
