Three different bags of pretzels are sold at the store. wich bag of pretzels is the best buy a) 10 ounces for $ 1.10 b) 12 ounces for $ 1.38 c) 6 ounces for $ 0.84

Bag (a) of pretzels is the best to buy.

Step-by-step explanation:

Three different bags of pretzels are sold at the store.

We are asked to find which bag is the best to buy?

Since the bag whose per unit cost is less will be profitable to buy.

Bag a)

10 ounces cost $ 1.10

Hence cost of 1 ounce= $ (1.10/10)= $ 0.11

Bag b)

12 ounces for $ 1.38

Hence, cost of 1 ounce= $ (1.38/12) = $ 0.115

Bag c)

6 ounces for $ 0.84

Hence, cost of 1 ounce=$ (0.84/6)=$ 0.14

Hence, the bag of pretzels which is best to buy is bag (a).

( since the per unit cost is minimum in bag (a) as compared to other two bags)

step-by-step explanation:

all of the other ones have a specific pattern

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
