The scientists in a laboratory company raise amebas to sell to schoolsfor use in biology classes. They know that one ameba divides into twoamebas every hour and that the formulat= log_2Ncan be used to determine how long in hours,t, it takes to produce a certain number

of amebas,N. Determine, to the nearest tenth of an hour, how long it takes to produce 10,000 amebas if they start with one ameba.
