Question: Jane is painting her fingernails. She applies a base coat that takes 2 minutes to dry, two color coats that take 3 minutes each to dry, and a clear top coat that takes 5 minutes to dry. How many minutes total does Jane spend waiting for her nail polish to dry?
Answer with step-by-step thinking: First figure out how long both color coats will take to dry: 3 minutes * 2 = 6 minutes. Then add up the time for the base coat, top coat, and color coats: 6 minutes + 2 minutes + 5 minutes = 13 minutes.
So the answer is 13.

Question: A farm is growing corn in 2 fields. One of the fields has 13 full rows of corn cobs, and the other field has 16 full rows of corn cobs. If each row contains 4 corn cobs, how many corn cobs has the farm grown?
Answer with step-by-step thinking:
In the first field, there are 13 rows * 4 corn cobs / row = 52 corn cobs. In the second field, there are 16 rows * 4 corn cobs / row = 64 corn cobs. So the farm has grown a total of 52 corn cobs + 64 corn cobs = 116 corn cobs.
So the answer is 116.
