<human>:  Whenever Katie and her family eat donuts, they need some coffee to dunk them in. She notices that for each donut they need 2 ounces of coffee. Every pot of coffee she makes contains 12 ounces and costs $3 to make. If her family finishes 3 dozen donuts, how much do they spend on coffee?
<bot>: How many donuts does her family eat? ** He family eats 36 donuts because 3 x 12 = <<3*12=36>>36
How many ounces of coffee do they need? ** They need 72 ounces of coffee for these because 2 x 36 = <<2*36=72>>72
How many pots of coffee do they need? ** This is equal to six pots of coffee because 72 / 12 = <<72/12=6>>6
How much will it cost to make the coffee? ** This will cost $18 to make because 6 x 3 = <<6*3=18>>18
