Question 852826
On day {{{ n }}}, He collected {{{ 4*4^(n-1) }}} pounds
{{{ 1000 = 4*4^(n-1) }}}
{{{ 4^(n-1) = 250 }}}
{{{ 4^n / 4  = 250 }}}
{{{ 4^n = 1000 }}}
{{{ n*log(4) = log( 1000 ) }}}
{{{ n = 3/log(4) }}}
{{{ n = 3/.6021 }}}
{{{ n = 4.98 }}}
On the 5th day he collected over 1,000 pounds
check:
{{{ n = 5 }}}
{{{ 4*4^(5 - 1) }}}
{{{ 4*4^4 }}}
{{{ 4^5 = 1024 }}}
OK
