Answer:
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.
