(C) \$37,500
(D) \$42,500
(E) \$50,000

Total = 50*45000 = 2250000

Total of 10 wealthiest = 10 * 75000 = 750000

Remaining amounts = 2250000 - 750000 = 1500000

1500000 / 40 = 37500

(A) \$27,500
(B) \$35,000
(C) \$37,500
(D) \$42,500
(E) \$50,000

total income sum = 45000*50 ; 2250000
wealthiest income sum = 75000*10 ; 750000
so 40 customers sum = 2250000-750000= 15*10^5
avg 15*10^5/40 = \$37,500

IMO C
