The number of pretzels needed by her will be 60 for the ratio 3 : 5.
We are given that the ratio of cheddar crackers to pretzels in the snack mix is 3 : 5.
Now, we also know that Genesis has 36 cheddar crackers.
Now let the number of pretzels be x.
So ATQ, we get that:
3 : 5 = 36 : x
Solving it further, we get that:
3 / 5 = 36 / x
Cross multiplying the terms, we get that:
3 x = 36 × 5
3 x = 180
Finding the value of x, we get that:
x = 180 / 3
x = 60.
Therefore, the number of pretzels needed by her will be 60 for the ratio 3 : 5.
