Answer:
Let's define x as the number of text messages send.
y as the number of 1,000 minutes talk per month.
(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.
> The equation for Dash is:
C1(x, y) = $80
>The equation for AB&C
C2(x,y) = $0,20*x + $55*y
> Horizon
C3(x,y) = $0.10*x + $75*y.
Now, which company you should go for?
Well, it depends on the values of x and y that you have.
if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.
if you usually talk, you may want to go with AB&C because the slope for y is smaller.
If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y

Answer:
Rani will use 3/2 cups of white rice for 3 cups of milk.
<h3>What is termed as unitary method?</h3>
"It is a method in which we obtain the value of a single unit by subtracting the value of multiple units and thus the value of multiple units by subtracting the value of a single unit."
- The value of several things is given in the unitary method, and we must either figure out the significance of more or lesser things.
- To do so, we must first determine the value of one item by division and then determine the value of ever more or fewer items by multiplication.
Now, for the given question;
1 cup of white rice is required for every 2 cups of milk by Rani.
Thus,
2 cups of milk ------> 1 cup of white rice.
So, using unitary method. Divide both side by 2.
1 cups of milk ------> 1/2 cup of white rice.
Now, calculate for the 3 cups of milk.
multiplying both side by 3.
3 cups of milk ------> 3/2 cup of white rice.
Therefore, the 3/2 cups of white rice required for the 3 cups of milk.
