A bottle holds 48 tsp of vanilla. The

amount A of vanilla remaining in the bottle decreases by 2 tsp per batch b of cookies.

Write a function rule to represent this situation. A=__

How much vanilla remains after 12 batches of cookies? __ tsp

1 answer

The function rule to represent this situation is:

A = 48 - 2b

After 12 batches of cookies, we substitute b = 12 into the equation:

A = 48 - 2(12)
A = 48 - 24
A = 24 tsp

Therefore, 24 tsp of vanilla remains after 12 batches of cookies.
