Jonas Buckley · Answer 1

B) $96.75

Step-by-step explanation:

5pound bag cost = $13.85

10pound bag cost = $20.43

25pound bag cost = $32.25

The least quantity of bag the customer can by is 65 pounds = (2*25 pound) + 10 pound + 5pound = $98.78

But careful examination will show actually that since the most the customer can buy is 80 pound, then buying 25pound in three places give him even a lot cheaper than buying the least amount

75 pound = 3*25 pound = 32.25*3 = $96.75.

Therefore the least amount in cost the customer can buy is $96.75
