Abox of national brand cornflakes is $2.09 for 12 ounces. a box of store label cornflakes is $3.09 for 20 ounces. a) what is the unit price for each? b) assuming both brands taste equally good, which is the better buy and why? c) if you have a 30cent-off coupon for the national brand, which is the better buy and why?

A)

B) The larger box is cheaper per ounce.

C) 2.09 – .30 = 1.79 for 12 ounces. So than $1.79/12= .15/oz.

They  would both be the same so there would be no better deal.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
