An online movie streaming plan has no annual fee bu charges $4.25 per movie watched. another plan charges an annual fee of $36 plus $3.50 per movie watched. for how many movies is the cost of the plan the same?

b. 10=9.1+0.2x

step-by-step explanation:

that's it

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
