neopets lenny conundrum help?

Osiri was having a hard time attracting customers to her pottery shop, so she asked the Lenny Conundrum writer if her shop could be featured in this week's Lenny Conundrum. And obviously, since you're reading this, the Lenny Conundrum writer agreed. And her gift of a Jewel Encrusted Bowl had nothing to do with it, even though it will look beautiful in my Neohome.


Anyway, the first day after the Lenny Conundrum appeared, she had 13 customers. The next day, she had 14. The next day, 95 customers! And the day after that, 62.

How many total customers did she have in the first twenty days after the Lenny Conundrum appeared?
