Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
Answer:
they both will have a product containing the number three and they are different because .3 times .01 will have a lesser amount for a product
Step-by-step explanation:

Given:
Cost of 1 digital song = $1.05
Cost of 2 digital song = $2.10
Cost of 5 digital song = $5.25
To find:
The equation and the cost of 25 downloaded digital songs.
Solution:
Let us take two points (1, 1.05) and (2, 2.10).
Here 
Slope:


m = 1.05
Using point-slope formula:



Add 1.05 on both sides, we get

Here x is the independent variable and c is the dependent variable.
So that substitute x = n and y = c.

The equation is c = 1.05 n.
Substitute n = 25 in the equation.


The cost of 25 songs is $26.25.
14.4 is going to be your answer
