Matilda always eats at least one of the following for breakfast: cereal, bread, or yogurt. On Monday, she is especially picky. I
Annette [7]

Answer:

Matilda eats Cereal on Monday.

Step-by-step explanation:

Breakfast options for Matilda are: Cereal (C), Bread (B) or Yogurt (Y).

<u>Condition 1:</u> If she eats cereal and bread she also eats yogurt.

                     Then Matilda's breakfast combination is: C + B + Y.

<u>Condition 2:</u> If she eats bread or yogurt, she also eats cereal.

                     Then Matilda's breakfast combination is: C + B or C + Y.

<u>Condition 3:</u> She never eats both cereal and yogurt.

                   Then Matilda's breakfast combination does not include is: C + Y.

<u>Condition 4:</u> She always eats bread or cereal.

                  Then Matilda's breakfast combination always includes is: C or B.

If Matilda eats bread (B) then according to Condition 2 she eats cereal (C) also. And since she eats both C and B she eats yogurt (Y) also.

But according to Condition 3 Matilda never eats both cereal and yogurt.

Hence she can never have all three for breakfast.

She cannot eat bread (B) alone [according to Condition 2], Matilda is left with only one option, i.e. Cereal (C).

Thus, Matilda eats Cereal for breakfast on Monday.

A 2 pound box of salt sells for $.89 and a 5 pound box sells for 2.09. What is the linear equation for this?
castortr0y [4]
Y = ax + b;

0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;

y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.
