Answer:do you know the Volume formula
Step-by-step explanation:
The linear function representing the above function is
F=0.4x+2
Step-by-step explanation:
Let the total monthly cost be represented as $ F
Let the number of songs downloaded in a month be x
Given: cost of downloading one song= $ 0.40
Monthly subscription fee (one time monthly) = $ 2
Hence total monthly cost-
Total monthly cost= cost of downloading “x” songs + monthly subscription fee
Total cost of downloading “x” songs monthly= number of songs downloaded* cost of downloading one song
Total cost of downloading “x” songs monthly=$ 0.4x
Hence Total monthly cost= 0.4x + 2
We have assumed total monthly cost as “F”
F=0.4x+2
The answer is all of the students are members of the frequent visitor program.
Let x be the number of students that are members of the frequent visitor program.
Let y be the number of students that are not members of the frequent visitor program.
There are in total 19 students: x + y = 19
x students will pay $11, y students will pay $13 for the ticket. Totally, it will be $209: 11x + 13y = 209
Now, we have the system of two equations:
x + y = 19
11x + 13y = 209
____________
Use the method of substitution:
x + y = 19
⇒ x = 19 - y
____________
11(19-y) + 13y = 209
11·19 - 11·y + 13y = 209
209 - 11y + 13y = 209
____________
Rearange:
13y - 11y = 209 - 209
2y = 0
⇒ y = 0
Since y = 0, x = 19:
x + y = 19
x + 0 = 19
x = 19
This means that all of the students in the group are members of the frequent visitor program.
This first one where Jeremy is already in 250miles. X is the amount of time.
