... go with the flirty route, the coin metamorphosing him correspondingly.

...not listen to Nabiki's advice whatsoever. Sure, Nabiki was an actual girl, but out of the two of them, Ranma had done way more flirtin' with guys and he wasn't exactly going to change his MO because Nabiki though that playin' dumb would work better. Besides, Ranma was kinda sensitive about his intelligence, and acting dumb on purpose wasn't something he would ever be caught doing. After stretching for a second and reaching down to adjust the cups of the costume, making his boobs spill out a little more to really give the guys what they wanted, Ranma walked up to the first guy who walked by, who looked like a salaryman.

Ranma ran up to the guy in a suit, making sure to put enough effort into his steps that his boobs were jiggling like crazy, then stopped closer than was normally appropriate and gave him a winning smile. "Excuse me, sir, but I'd really like it if you could join me? Our martial arts dojo is a great place to stay fit, and I'd love your company♡" To properly accentuate that last word, Ranma even fluttered his eyelashes as he held out a flyer.

The guy blushed, and looked between Ranma, his breasts, and the flyer. "I...uh..." he stammered, and Ranma knew he'd caught the guy: hook, line, and sinker. Take that, Nabiki, who's the master of seduction now?! "I've got to get to work, bye!" With that, the salaryman ran away, without taking the flyer still in Ranma's hands. He stared at it, confused. How did that not work? Was Nabiki right? No, no that couldn't be it. Maybe he just needed to slut it up more, that had to be it.

Seeing another rube walking down the street, Ranma sashayed up to him, ready to do whatever it took to get him to take a flyer. But the coin nestled between his boobs hadn't let his earlier thought go, and as he walked his breasts grew a little larger, a little bouncier, and his already beautifully feminine face found itself covered in make-up that drew men's eyes and made them wonder what she was willing to offer. "Hello there, I'm a part of the Anything Goes Martial Arts Dojo, and I'd love it if you could join. I'll be there every day~"

This particular sucker looked like a university student out on a walk, and he was much less shy about Ranma's flirting. "Oh really," he said with a not very charming smile, "what exactly would we be doing, at this dojo?"

Normally, Ranma would just insinuate something vague and sexy, but that had't really worked on the last guy, now had it? No, he was going to need to be specific. Leaning forward, Ranma whispered into his ear, "Well, we'd train of course, but that does have a tendency to get me all hot and bothered. Maybe when no one's looking, you and I can sneak out and relieve some tension in a different way, if that's okay with you, cutie." It was only after the words left his mouth that Ranma realized that he'd basically just promised this guy sex. He was a guy, he wasn't going to do that! Then again, it wasn't like he had to deliver on the promise, and if he did, who would ever find out? To no one's surprise, the guy took the flyer and winked at Ranma, and he was even reading it while walking down the street. Alright, one down, one hundred and ninety-nine to go!

By the time the sun was setting, Ranma had actually managed to hit that golden number Nabiki had asked for, and along the way he'd promised a number of sexual favors to them. Nabiki was glad, confused a little, but genuinely happy, and reminded Ranma of the fact that what had just happened was only step one. Tomorrow, he'd have to actually teach these yahoos and make the dojo, and by extension Nabiki, money while doing it.
