<human>:  Jaylen has 5 carrots and 2 cucumbers. Jaylen has twice as many bell peppers as Kristin. Jaylen has 3 less than half as many green beans as Kristin. If Kristin has 2 bell peppers and 20 green beans, how many vegetables does Jaylen have in total?
<bot>: How many bell peppers does Jaylen have? ** Jaylen has 2 * 2 = <<2*2=4>>4 bell peppers
How many green beans does Jaylen have? ** Jaylen has (20 / 2) - 3 = <<20/2-3=7>>7 green beans
How many vegetables does Jaylen have in total? ** Jaylen has a total of 4 + 7 + 5 + 2 = <<4+7+5+2=18>>18 vegetables
