The thing about a shark is--teeth, Said shark expert my brother Keith. To study sharks, he happily Set said to greet them out at sea. Keith counted the first pointed row-- Eight hundred twelve! Four rows to go. If each of those had half as many. How many teeth would equal plenty? Before Keith finished adding, he Was swallowed by shark dentistry. How many teeth did the shark have?
812 + 4 (1/2)(812) = 812 + 2(812) = 3 * 812 = 2436 shark teeth
Add the number of teeth that Keith has = 32
The shark now has 2436 + 32 = 2468 teeth
