Charlie just bought 8 bags of 14 cookies each. He already had 9 cookies in a jar. How many cookies does Charlie have now?

he has 121 cookies now

Step-by-step explanation:

8 times 14 plus 9

8 times 14 = 112 + 9 = 121

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
