Peter bought 8 lemons for 6 dollar. what was the cost for 1 lemon?

6 dollar divided per 8 lemons = $0.75

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

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong
