Answer
24tbs of vanilla remain
Work Step by Step
The function would be y=-2b+48 because we start with 48 vanilla teaspoons. We lose 2 tablespoons of vanilla every time we make a batch of cookies. To find the amount of vanilla remaining after 12 batches, plug in 12 for b and solve:
y=-2b+48
y=-2(12)+48
y=-24+48
y=24
There are 24 teaspoons of vanilla left after you make 12 cookie batches.
