Human: There were 80 cars in a parking lot. At lunchtime, 13 cars left the parking lot but 5 more cars went in than left. How many cars are in the parking lot now? Assistant: 
How many cars are in the parking lot after 13 left? ** There are 80 - 13 = <<80-13=67>>67 cars in the parking lot after 13 went out.
How many cars went in the parking lot at lunchtime? ** 13 + 5 = <<13+5=18>>18 cars went in the parking lot at lunchtime.
How many cars are in the parking lot now? ** So, there are 67 + 18 = <<67+18=85>>85 cars in the parking lot now.
