D. 0.482 lb of nuts and 0.393 lb of dried fruits

Step-by-step explanation:

Given :

Cost of nuts = $12/ lb

Cost of dried fruit = $8.50/lb

Cost of Pretzels = $3/lb

Cost of snack mix = $9.50/lb

Amount of pretzels in the snack mix = 2 oz

To find :

Amount of nuts = ?

Amount of dried fruits = ?

Solution:

Let the amount of nuts and dried fruits be x and y lb respectively.

w.k.t, 1 lb = 16 oz

Since, 2 oz of pretzels is present in the snack mix, the total amount of nuts and dried fruits in the snack mix is 16-2=14 oz.

∴ x + y = 14/16  = 0.875                     > a

2 oz of pretzels cost = (3/16) * 2 = 3/8 = $0.375

So, the cost of nuts and dried fruits in the snack mix = 9.50-0.375=$9.125  

∴12 x + 8.5 y = 9.125 > b

Now, solving equations a and b, we have

x = 0.482 , y = 0.393

∴ 0.482 lb of nuts and 0.393 lb of dried fruits are present in 1 lb of the snack mix.

So, the answer is

D. 0.482 lb of nuts and 0.393 lb of dried fruits
