Beatrice is shopping for a new TV. First she looks at 8 TVs at one store in person. Then she looks at three times as many TVs at an online store. She looks at more TVs on an auction site online. If Beatrice looked at 42 TVs in all, how many did look at on the auction site? Let's think step by step and output the final answer after "####".

Beatrice looked at 3 x 8 TVs at an online store = <<3*8=24>>24 TVs.
She looked at 8 TVs in person + 24 TVs online = <<8+24=32>>32 TVs.
Beatrice looked at 42 TVs in all - the 32 she looked at = <<42-32=10>>10 TVs she looked at on an auction site.
