Abox of national brand cornflakes is $2.09 for 12 ounces. a box of store label cornflakes is $3.09 for 20 ounces. if you have a 15% off coupon for the national brand, which is the better buy?

It will be better to buy the national brand cornflakes as it is less costlier.

Step-by-step explanation:

A box of national brand cornflakes is $2.09 for 12 ounces.

So, per ounce cornflakes of national brand costs dollars.

Now, if I have a 15% off coupon for the national brand, then the per-ounce cost for national brand cornflakes will be dollars.

It is given that a box of store label cornflakes is $3.09 for 20 ounces.

Then the per-ounce cost for store label cornflakes will be dollars.

Therefore, it will be better to buy the national brand cornflakes as it is less costly. (Answer)

what is the question here

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
