A wholesaler bought 1,200 radios for $18 each. The wholesaler sold 60 percent of the radios for $30 each and the rest for $15 each. What was the wholesaler’s average (arithmetic mean) profit per radio?

Option A:

$2

Option B:

$3

Option C:

$4

Option D:

$5

Option E:

$6

Option E is the correct answer.

60% of radios were sold at $30 and 40% at $15.

Average selling price = (30*0.6 + 15*0.4)/1 = 24

Average cost price = $18

Average profit = $6
