commission=rate*(sales-3000)
c=r(s-3000)
r=c/(s-3000)
r=420/(16000-3000)
r=420/(13000)
r=~0.0323=3.23%
3.2%

commission=rate*sales
c=r*s
total salary=commission+1150+120
w=c+1270
c=w-1270
c=3250-1270
c=$1980

r=c/s
r=1980/35000
r=~5.657%

If she is paid only on sales OVER $3,000 the she must not get paid at all until she reaches that sales figure.  So, subtract the @3,000 from the total saes of $16,000 and you get $13,000 of sales on which she was compensated.  If she made $420 on $13,000 of sales, it's jsut simple math.  420/13000 = 3.2%, rounded to the nearest 1/10%.  Simple, eh?

Martin's health care has nothing to do with this problem as stated, so forget it.  Same easy principles apply.  $3250-$1150 = commissions = $2100.  If he sold $35000 worth of goods then the equation is 2100/35000 = 6%, exactly like the first problem.  Get it now?
