For this chain-of-thought reasoning and answer, what was the question?
First find the total number of pies Marcus bakes: 5 pies / batch * 7 batches = 35 pies. Then subtract the number of pies Marcus drops: 35 pies - 8 pies = 27 pies.
A: 27
Q: Marcus can fit 5 pies in his oven at once. He bakes 7 batches of pies, then slips and drops 8 of them. How many pies are left?
