Answer:
The weight of the misture if of 7 lbs.
Step-by-step explanation:
The total misture is T.
The ratio means that:
Walnuts are responsible for 7/(7+2+5) = 7/14 = 1/2 of the weight.
Peanuts are responsible for 2/(7+2+5) = 2/14 = 1/7 of the weight.
Chocolate chips are responsible for 5/(7+2+5) = 5/14 of the weight.
2.5 lbs. of chocolate chips were used for making it:
This means that:
[tex]\frac{5T}{14} = 2.5[/tex]
[tex]5T = 14*2.5[/tex]
Simplifying by 5
[tex]T = 14*0.5[/tex]
[tex]T = 7[/tex]
The weight of the misture if of 7 lbs.
