You can buy (Deal A) a 2-pound loaf of bread for $2.50 or (Deal B) a 2-pack of 1.5-pound loaves for $3.30. What was the Unit Price of the better deal $_per pound (input numbers and decimals point only)

Deal B is the better deal with $1.10 per pound

Step-by-step explanation:

Deal A:

2 pounds = $2.50

1 pound = $ 1.25

Deal B:

2 packs of 1.5 pound loaves= $3.30

Which means,

3 pounds = $3.30

1 pound = $1.10

The better deal is the Deal B with $1.10 per pound

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
