Gloria talked on her cell phone for 320 min the 1st month 2nd she did 243 min 3rd she did 489 she has to pay $25 for every 200 min

She has to pay $131.50 for the months she was on her cell phone.

Step-by-step explanation:

Basically, you add 320+243+489 = 1052

Then you divide 1052 with 200 which you get 5.26

Finally, you multiply 5.26 with $25 which equals 131.50

I hope this is the answer you are looking for!

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
