Elena makes banana bread and nut bread to sell at the market. a loaf of banana bread requires 2 cups of flour and 2 eggs. a loaf of nut bread takes 3 cups of flour and 1 egg. elena has 12 cups flour and 8 eggs on hand. if she makes $1.50 profit per loaf of banana bread and $2 per loaf of nut bread, how many loaves of banana bread and nut bread could she make that will maximize her profit? a. elena could make 0 loaves of banana bread and 4 loaves of nut bread to maximize her profit. b. elena could make 2 loaves of banana bread and 3 loaves of nut bread to maximize her profit. c. elena could make 3 loaves of banana bread and 2 loaves of nut bread to maximize her profit. d. elena could make 1 loaf of banana bread and 5 loaves of nut bread to maximize her profit.

Let x be the number of loaves of banana bread and y be the number of loaves of nyt bread Elena makes.

1. A loaf of banana bread requires 2 cups of flour and 2 eggs, then x loaves require 2x cups of flour and 2x eggs.

2. A loaf of nut bread takes 3 cups of flour and 1 egg, then y loaves require 3y cups of flour and y eggs.

3. Elena has 12 cups flour, then

2x+3y≤12.

4. Elena has 8 eggs, then

2x+y≤8.

5. If she makes $1.50 profit per loaf of banana bread and $2 per loaf of nut bread, then she makes total profit of $(1.50x+2y).

The solution of system of two inequalities

is represented in the attached diagram.

The maximal profit can be obtained at point (3,2), where

correct choice is C (Elena could make 3 loaves of banana bread and 2 loaves of nut bread to maximize her profit)

3x + 4y -25 =0 represents the amount of change sianna should recieve

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
