Abby can buy 8-pound bag of dog food for $7.40 or a 4-puond bag of the same dog food for $5.38.which is the better buy?

We can find price of each case and then we can decide

Case-1:

Abby can buy 8-pound bag of dog food for $7.40

so, for 8 pound bag = $7.40

now, we can find price

Case-2:

a 4-puond bag of the same dog food for $5.38

So, for 4 pounds = $5.38

now, we can find price

So, we can see that cheapest price is $0.925 per pound

so, first case is better

so,

8-pound bag of dog food for $7.40..........Answer

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

38 was the other number of your question.
