Question 1016810
The time (in minutes for which Sharee walks each day in week {{{n}}} can be modeled by the equation
{{{T = 10 * 2^((n-1))}}}
We want to find the value of {{{n}}} that makes {{{T=160}}} , so our equation is
{{{160= 10 * 2^((n-1))}}}
{{{160/10= 10 * 2^((n-1))/10}}}
{{{16=2^((n-1))}}}
{{{2^4=2^((n-1))}}}
{{{4=n-1}}}
{{{4+1=n}}}
{{{highlight(n=5)}}}
