What is the additive identity for rational numbers?

Vanyuwa [196]

Answer:

Step-by-step explanation:

The rational number 0 is the additive identity for rational numbers.

As,

If we add any rational number to zero we get that number itself.

E.g.

$0 + \frac{1}{2} = \frac{1}{2}$

and

$0 + ( - \frac{5}{6} ) = ( - \frac{5}{6} )$

(20 points) A 2-liter bottle of soda (67.6 ounces) costs $1.89. A case of twelve 12 ounce

horrorfan [7]

Answer:

Unit price of a 2-liter bottle of soda: $\$0.028\ per\ ounce$
Unit price of a case of twelve 12 ounce cans: $\$0.021\ per\ ounce$
The better bargain is the case of 12 ounce cans.

Step-by-step explanation:

Let be "x" the unit price (price/ounce) of the soda in the 2-liter bottle and "y" the unit price (price/ounce) of the soda in the case of twelve 12 ounces cans.

According to the data provided in the exercise, you know that:

1. The 2-liter bottle of soda is equal to 67.6 ounces.

2. That bottle costs $1.89

Then, the unit price is:

$x=\frac{1.89}{67.6}\\\\x\approx0.028$

3. There are 12 ounce cans in the case. Then the total ounces is:

$12\ oz*12=144\ oz$

4. It costs $2.99. So the unit price is:

$y=\frac{2.99}{144}\\\\y\approx0.021$

Since:

$y$

The better bargain is the case of 12 ounce cans.
