<h3>
The monthly cost of cell phone is A = 40 + 0.005 m</h3>
Step-by-step explanation:
The monthly fixed charges by mobile company = $40
The cost of sending each text message = 0.05 cents
Now, 100 cents = 1 dollar
⇒ 1 cent =$ 
⇒ 0.05 cent s =$ 
Also, the number of text messages send = m
So, the cost of sending m text message = m x ( cost of 1 text )
= m x ( $ 0.0005) = 0.0005 m
Now, Total bill = Fixed rate + cost of m texts
⇒ A =$40 + $ 0.0005 m
Hence, the monthly cost of cell phone is A = 40 + 0.005 m
Answer: They don’t score any points, because since micheal scored 5 points, but Daniel lost those 5 points. They still have 0
Step-by-step explanation:
“Rate of change” means the same as “slope.”
In algebra, we use the word "slope" to describe how steep a line
is and slope can be found using the ratio rise/run between
any two points that are on that line.
Starting from the point that has the coordinate (-1, -1),
we rise go 1 unit down so our rise is -1 and run 3 units.
So our slope or rise/run is -1/3.

Answer:
0.10x + 0.13y = 10780
x + y = 100000
x = 74000 --------------10%
y = 26000 --------------13% (more risky)
