Answer:
3p + 10; 40 minutes
Step-by-step explanation:
It takes 3 minutes to shape one pot.
It takes 3p minutes to shape p pots.
A batch of pots has p pots and takes 10 minutes in the kiln.
The total time it takes to make 1 batch is the time to shape the pots, 3p, plus the time in the kiln, 10 minutes.
The expression is
3p + 10
For a batch of 10 pots, p = 10.
3p + 10 = 3(10) + 10 = 30 + 10 = 40
Answer: 3p + 10; 40 minutes
