Answer:
To sum up, we looked at the important amount devided by the total amount. Finally we solved for p. Which gave us p=75. Furthermore 75 percent of the trail mix is made up out of berries.
Explanation:
So the main equation with percentages is W/G = p/100.
So First we look at G. G describes the total amount. In this case the total amount of teaspoons is four. Four because we have three tablespoons of berries and one tablespoon of nuts. That is four tablespoons.
Now we can go further to find out what W is. 2 is the important amount. In the question we are supposed to look at the amount of berries is the trail mix. Which gives us the value three.
So far our equation has no unknowns anymore 3/4=p/100. We multiply both sides of the equation with 100 3*100/4=p. Thus p = 300/4=150/2=75.
