Question 1129151

given: 


{{{(B+0.015*t)/0.022=N}}}


if the BAC is{{{ 0.17}}} => in your formula is only {{{B}}}; so, {{{B=0.17}}}
and, if the time is {{{1.5}}} hours=>{{{t=1.5}}}


substitute both in given formula


{{{(0.17+0.015*1.5)/0.022=N}}}


{{{(0.17+0.0225)/0.022=N}}}


{{{0.1925/0.022=N}}}


{{{8.75=N}}}
