Question

Select the correct answer from each drop-down menu.

Answer 1

The correct answers are:

Not change; not change; and triple.

Explanation:

A change in the amount he pays on other ingredients will not change the amount he pays for potatoes.  This means m does not change.

A change in the price of potatoes will not change the amount he pays for the other ingredients.  This means b does not change.

A change in the price of potatoes will, however, change the amount he pays total for the potatoes.  Tripling the price of potatoes will cause the amount he pays total for the potatoes to triple as well.
