Answer:
25
Step-by-step explanation:
Given that:
Initial payment done for buying the phone = $50
Charges per month for the phone = $25 per month
To find:
The equation to represent the situation and its slope.
Solution:
First of all, let us assume that
represents the number of months for which monthly is to be made.
Charges paid for one month = $25
Charges paid for
months = $25
Total cost of the phone = Initial payment + Charges paid for
months

It is a linear equation between two variables
and
.
This equation can be compared with slope intercept form of a line.
Slope intercept form of a line is represented by:

is the slope.
On Comparing, we get:

Therefore, the slope is <em>25</em>.
Answer:
I'm doing the same thing and, I don't understand it either.
Step-by-step explanation:
You are correct. For each of the three possibilities for their second day, there are two possibilities for the third day.
The total number of possibilities is 3*2 = 6.
