(108+72+95+x)/4=91
(347+x)/4=91
347+x=91•4
347+x-347= 364-347
X=17
She must score a 17 to get a mean of 91

Answer:

$185

Step-by-step explanation:

The first ten suits sold for 10×$250 = $2,500

commission = 5% of $2,500 = 0.05×$2,500 = $125

The next three suits sold for 3×$250 = $750

commission = 8% of $750 = 0.08×$750 = $60

Total commissions = $125+$60 = $185
