you have a carton of 48 eggs. you check the weight of the carton and it is 28 lbs. if you give 5 brothers 11 of your eggs how much would their carton wiegh?

divide by 5

step-by-step explanation:

60/5 = 12

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

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
