Calculate the number 2370

A blonde and a redhead have a ranch. They have just lost their bull. The women need to buy another, but only have $500. The redhead tells the blonde, "I will go to the market and see if I can find one for under that amount. If I can, I will send you a telegram." She goes to the market and finds one for $499. Having only one dollar left, she goes to the telegraph office and finds out that it costs one dollar per word. She is stumped on how to tell the blonde to bring the truck and trailer. Finally, she tells the telegraph operator to send the word "comfortable." Skeptical, the operator asks, "How will she know to come with the trailer from just that word?" The redhead replies, "She's a blonde so she reads slow: 'Come for ta bull.'"
