Granola sells for 2.75 per pound. how much will 7 pounds cost?

$19.25

Step-by-step explanation:

One lb of granola sells for $2.75. You are trying to find how much 7 pound costs. Multiply 2.75 with 7:

($2.75/1 lb of granola) x (7/7) = (2.75 * 7/7 lb of granola)

Simplify:

2.75 * 7 = 19.25

7 lbs of granola costs $19.25

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

i think is g(1)=-1.

hope that i can
