The richmond family restaurant has several types of hamburgers on its menu. the more hamburgers their customers order, the more hamburger buns they will use.

h = the number of hamburgers ordered
b = the number of hamburger buns used

which of the variables is independent and which is dependent?

INDEPENDENT  variable  : h = the number of hamburgers ordered

DEPENDENT variable :   b = the number of hamburger buns used  

Step-by-step explanation:

Independent Variables: The type of variables whose change is NOT DEPENDENT on the change of other variables are known to be independent variable.

Dependent Variables: The type of variables whose change is DEPENDENT on the change of other variables are known to be independent variable.

Now here:

h = the number of hamburgers ordered

b = the number of hamburger buns used

The number of buns used depend upon the number on the buns ordered.

More buns Ordered ⇒  More buns Used

⇒  Used buns is dependent upon the order.

Hence, h = the number of hamburgers ordered  is INDEPENDENT.

b = the number of hamburger buns used    is DEPENDENT variable.

the correct answer is 5 6 and 7
