This is due tomorrow ! i know im stupid but i need ! lol

From Walmart, you have to buy at-least= 50/8 = 6.25 = 7 [round-off to larger direction value ]
So, it would cost = 7 * 2.99 = $20.93

From Sam's club, you have to buy at-least= 50/12 = 4.16 = 5 [round-off to larger direction value ]
So, it would cost = 5 * 3.19 = $15.95

In short, Sam's club offers the better deal.

Now, we can spend our minimum expense, by buying 3 pcs. of bun from Sam's club and 2 from walmart.
In that case, it would cost = 3*3.19 + 2*2.99 = $15.55

Hope this helps!

If you buy 5 bags in Sam's Club you will have 60 buns and it will cost $15.95. And if buy 7 bags in Walmart you will have 56 buns and will cost $20.93. And if you combine them you will need 3 bags of Sam's Club and 2 bags of Walmart you will have 52 buns and will cost $15.55. So your best choice answer you have to decide to combine 3 from Sam's club and 2 from Walmart to get the best offer. Hope this helps!! ;-)
