Last year the range of the annual fees of the 50 courses in a college was $300. If the annual fees of each of the 50 courses this year is 10 percent greater than it was last year, what is the range of the annual fees of the 50 courses this year?	Select the correct option:
A) $270  B) $300  C) $330  D) $360  E) $630
let the lowest fees x.   Therefore, highest fees is x +300.   Now fees of each course is increased by 10%.   Therefore the fees will remain arranged in the same order as before.   or Lowest fees = 1.1x and Highest = 1.1 * (x+300)   or Range = highest - lowest = 1.1 * (x+300) - 1.1x   = 330, Hence, $330
