Question 956549: Kate is a salesperson in a retail store and earns $40 per week plus 8% of her weekly sales. If Kate earned $456 one week, what were her sales that week? Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! K=Kate's weekly earnings; S=sales
K=$40 +0.08S
K-$40=0.08S
(K-$40)/0.08=S For K=$456
($456-$40)/0.08=S
$416/0.08=S
$5200=S ANSWER: Her sales were $5200.
CHECK:
K=$40+0.08S
$456=$40+0.08($5200)
$456=$40+$416
$456=$456
