单选题 A retailer sells 5 shirts. The first 2 he sells for $64 and $39. If the retailer wishes to sell the 5 shirts for an overall average price of over $50, what must be the minimum average price of the remaining 3 shirts?
A. $49.00
B. $49.67
C. $50.00
D. $51.33
E. $55.50

【正确答案】 A

【答案解析】For the average price of 5 shirts to be over $50, the total price of the shirts must be at least $250. 250 minus the sum of the two sold shirts (64+39=103) equals 147. $147 divided by 3 equals $49.
