Question

Someone help with this math problem

Answer 1

She needs 1/6 almonds , 1/3 walnuts and 1/2 of raisins as a fraction of total trail mix.
So she spends $2.5 on almonds. $5 on walnuts and $10 on raisins (total $15)

so that is 2.5/12 =  0.208  pounds almonds
5 / 10.5 =  0.476 pound walnuts
10/4 =  2.5 pounds raisins

so total wieght of the trail mix is 3.19 pounds
