Best ResponseYou've already chosen the best response.0a + w = 1000; this means that: a = 1000w a(.20) + w(.15) = 1000(.17) (1000w)(.20) + .15w = 170 200  .20w + .15w = 170 .05w = 30 .05w = 30 w = 600 lbs a + 600 = 1000; so a = 400lbs lets see if it works..... 400(.20) + 600(.15) = 1000(.17) 80 + 90 = 170 170 = 170 ...its good :)
