12 mixed nuts packs
Explanation:
The box weighs 16 1/2 ounces
1 mixed nut = 1 3/8 ounces
let the number of fruit mixed nut in the box = y
1 mixed nut = 11/8 ounces
y = 33/2 ounces
cross multiply:


Answer:
7-2x=22-3x
-2x=15-3x (minus 7 from both side)
x=15 ( plus 3x from both side)
68% will be 1 standrd deviation either side of the mean so a reasonable estimate will be (25*0.68) / 2 = 8.5
