The after-school Activities Club charges $20 to join for the year. It charges a materials fee of $ 6 for each activity you choose. Write a linear function to model the cost, c, of joining the club and choosing t activities. Find the value of the function for t equals negative 3. Explain the meaning of this function value in terms of the situation.

Which linear function models the cost, c, of joining the club and choosing t activities?

A. c = 6t + 20
B. c = 6t - 3
C. c = -3t = 20
D. c = 20t = 6

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
