You observe the following running times for a program with an input of size N$.$

N time

$1,0000\mathrm{.}1$ seconds

$2,0000\mathrm{.}3$ seconds

$4,0002\mathrm{.}5$ seconds

$8,00019\mathrm{.}8$ seconds

$16,000160\mathrm{.}1$ seconds

Estimate the running time of the program $($in seconds$)$ on an input of size N $=80,000.$ use formula log$($T $($N$))=$ blogN $+$ c
