What is the sum of the multiples of 6 from 48 to 72, inclusive?	Choose the correct answer:
A) 500	B) 600	C) 700	D) 300	E) 400
The formula we want to use in this type of problem is this:   Average*Total Numbers=Sum   First, find the average by taking the sum of the F + L number and divide it by 2:   A = (F + L)/2   Second, find the total numbers in our range by dividing our F and L numbers by 7 and add 1.   (72/6) - (48/6) + 1   Multiply these together so what we show Average*Total Numbers=Sum   (48 + 72)/2 * (72/6) - (48/6) + 1 = Sum   60 * 5=
