Last week, emily and stephanie decided to see how fast they could sprint 300 meters. they asked their friend kevin to time them with a stopwatch. after 3.29 minutes, kevin agreed to time the runners. emily sprinted first and ran 300 meters in 58.81 seconds. when it was stephanie's turn, she sped off and completed the run in 50.61 seconds. how much faster was stephanie than emily in seconds?

8.2 seconds because they run the same distance so all you would do is subtract 58.81-50.61=8.2 seconds

(a)          21500(0.88) ᣔx
          y = A(1-r)ᣔx 
         = 21500 (1-0.12) ᣔx  
         = 21500(0.88) ᣔx
 
   (b)    $9,985
        21500(0.88) ᣔ6 = 9985
·      0.88ᣔ6 = 0.46440408
·      21500 *  0.46440408 = 9984.68 -> 9985                

I this right
